Davidson still wants to discuss Lobbyist contract and Leonard advised will be covered in Legislative committee update.
Kramer gave review of the Financial report for month ending June 30, 2014. The General Fund began with a balance of $116,862.73 and after revenues and expenses, ended with a balance of $117,361.91. The Debt Service Fund began with a balance of $13,360.28 and after revenues ended with a balance of $21,505.98. The Dam/Spillway fund started with a balance of $4,972,661.09 and after revenues and expenses, ended with a balance of $4,710,809.20. Motion to file financial reports by Burger, second by Davidson, all ayes, motion passed. Kramer also advised she received a payment from the DNR today for $463,254.40.
Kramer is asking for approval for the Lunda Construction payment of $265,484.06 and Stanley Engineering payment of $12,619.76 for a total of $278,103.82 to be reimbursed by the DNR. She is also requesting approval of $4,103.50 from Delaware County which is a 50% reimbursement for a Stanley Engineering billing. Burger made motion to approve request, Gifford second. All ayes, motion passed.
Leonard introduced Change Order #2 for opening the sluice gates for a time and material, not to exceed estimate of $4,649.63. Gifford, Schneider and Leonard approved the change order previously based on resolution 6.19.14.b and tonight Leonard is asking for full board approval. Motion by Kramer to approve Change Order #2, Gifford second. Burger questioned if Stanley and Colgan had given prior approval and Leonard indicated yes and noted such on the change order. All ayes, motion passed.
Burger advised he was contacted by the bank (Bank Iowa) that holds the LDRA Dredge loan. The bank has been notified by the bonding attorneys that they cannot continue to give a qualified tax exempt status without a recent public hearing by the city of Delhi. Lori Dolan from Bank Iowa and Burger produced a new schedule. Burger advised in the finance committee budget a $20,000 principal payment was included to get us back on schedule of paying principal in 2014. Dolan has indicated that the bank is not interested in lowering the interest rate until a couple of years of principal are paid. Burger forwarded the new schedule to the LDRA and they have accepted the new schedule. Leonard made motion for discussion on this topic, Kramer second. Leonard would like to see us have discussions with the bank to see if there are other viable options for an interest reduction and possible reductions in the principal. Gifford said it was his understanding that the bank was open to discussing alternatives. Burger said he had no problem with getting back together with the bank for further discussions. Burger made motion to table, Davidson second, all ayes, motion passed.
Kramer discussed the building across the street for possible use by the Trustees. Trustees toured the building and it looks like it is a viable alternative for us to use. Kramer is checking to confirm we can get Internet access in the facility. Kramer said 2 custodians and the superintendent would retain keys to the facility. Kramer said she believes they will be asking for just a one time payment. Burger says the building needs a new roof and we should understand the plan for that. Burger also indicated a 28E agreement would be in order to understand the agreements between us and the school board.
Finance committee – no update
Dam Construction/Timeline – Leonard said the water backup permit has been signed and is on its way to us. Colgan gave update and advised 3 weeks of rain did impact construction. Lunda has repaired the coffer dam and as of Monday, all of the extra water was drained down again. Lunda has been working on the concrete pier removal. An inspection of the silting basin floor shows it was intact and in good shape. The ordered gates may be delivered early. Phase II is ready to go out for bids. Gifford said Colgan’s pictures and reports are all posted to the District web site. Leonard said the construction committee members met with Colgan and discussed potential next steps for dredging. We should do core drillings and there will be recommendations coming to the board soon. Stanley is working to get an estimated cost of the primary areas of the lake bed. Colgan said we have the measurements of the tops of the sediment, but not the bottom. We need to know the depth of the sediment to know the volumes. The sand is less at Linden acres now than right after the breach but is building up at the Maples. Colgan said Stanley is putting together a bid proposal for us to hire someone to do the shallow borings.
Lake bed – Gifford did a kayak trip from Baileys Ford to Linden Acres for data collection and to identify which items have debris or tree issues. Gifford said he was surprised that there still is a significant tree issue and he is now in the process of working with the road associations to get the trees removed.
Legislative – 3 Trustees met with Gary Grant to talk about next steps. Leonard and Gifford gave presentation of where funds may be available and the benefits of advocacy. Burger suggested we have a work session at the next regular session to discuss how the lobbyists would work with us to accomplish it.
Property Management – There is a large wash out at the driveway of the office building down by the dam. Pat Dede suggested talking to the county for help.
Public comment – Ben Pasker indicated he thought erosion mitigation on the road should be done when the spillway is completed.
Ed Schmidt said he had provided a newspaper article regarding federal money for dredging. Kramer indicated she had the document and would forward to Leonard.
Jim Locke would like to see if the Trustees would agree to add LDRA information on our web site. The LDRA web site is having issues and the cost is too high for what needs to be done. The LDRA would like to abandon their web site. Gifford said it could be done with little trouble. Trustees will put this item on their next agenda.
Motion to adjourn by Burger, Kramer second, all ayes, motion passed. Meeting adjourned at 7:57 pm.

Delhi Dam Construction Progress Report #4
July 8, 2014
General Project Information
As has been discussed, Phase 1 was awarded to Lunda Construction Company, a large and experienced heavy structural midwest firm from Wisconsin in April 2014.
The DNR permit allowing the entire project to be constructed including Phase 2 has been received clearing the way to complete the project.
The important critical goal of Phase 1 work is to complete enough refurbishing work on the concrete structure to allow river water flow to be diverted from the current river bed through the concrete structure.
The timing of the Phase 2 bidding depends on being confident that Phase 1 work will be substantially complete by October 2014 allowing for the river to be diverted through the refurbished concrete structure. Right now in looks like Phase 2 work will be bid in July 2014 for an August 2014 contract mobilization to begin this work.
Project completion date is dependent on several factors including river flows being average or below, few weather extremes in the next 12 months, selecting a quality contractor for Phase 2 equivalent to our Phase 1 contractor and finally that the flow in the river at the time needed to refill the lake is sufficient.
Right now, again for planning purposes, we are planning for a July 4, 2015, date to resume enjoyment of Lake Delhi. It could be ready sooner if everything listed above goes great.
Specific Progress by Lunda on Phase 1 work through July 8, 2014 includes:
River flows are returning to more normal summer flows although they are still higher than average. This high river flow has slowed work on the project due to flooding of the upstream and downstream cofferdam areas. Temperatures have been from the 60’s to the mid 80‘s. Several rain events have also slowed progress.
The upstream cofferdam had to be strengthened following the high water event of the last week or so to reduce leakage to a tolerable amount.
Lunda has had to use Swamp Mats to bridge the mud on the upstream side of the dam so a track hoe could access the SW corner of the dam to set sheet piling in the existing upstream cofferdam to stop water from leaking into the Rock Anchor excavation.
Following driving sheet pile at this location, Lunda is drilling a grout curtain to stop water from entering the excavation hopefully allowing the area to be made ready to resume work on the rock bolting requirements for Phase 1.
Concrete sawing has continued on existing pier noses for their removal. Lunda has removed the top 6.5 ft. of the north pier nose and hauled it to the farm up X31 at the top of the hill.
Work Progress from June 20, 2014, to July 8, 2014
Excavation for the Rock Anchor Block is 90% complete and on hold until the area can be dewatered.
Lunda has finished assembling scaffolding and placing it on top of spillways for pier nose removal.
Eastern Iowa Concrete Sawing has been sawing on existing pier noses for removal.
B&J will continue pumping ground water from stilling basin.
Downstream Silt removal required for inspection is complete.
Finally, Lunda is constantly moving equipment and material to and from the site from their headquarters in Little Shute, WI, as needed due to the tight working conditions on the north side on the dam w here Phase 1 work is happening. Below the large track hoe shown above left the site today as it’s work is done for now. Sightseers are doing a good job of staying away from this work area and it is appreciated by the project.
Next Dam Construction Report – Thursday, July 24, 2014
Pat Colgan
Monday, June 23 was a lost work day due to all the upstream and downstream work areas being flooded from the previous Friday flood of over 8000 cfs. Normal flow for this time of year is 350 cfs. The upstream and downstream cofferdams remained in tact but repair work was required. Downstream the settling basin needed to be restored before the pumping could begin to pump out the loser area. By mid week the area was restored for construction.
Also, notice that the two sluice tubes near the bottom the first spillway were pressure water cleaned of all soil debris and the sluice gate on the upstream side of the dam was opened successfully. These tubes will be used on Phase 1 to keep the upstream area dewatered and for Phase 2 to help divert the river flow around the major cofferdam through these openings under the dam. This remains a pleasant surprise for the work required to restore Lake Delhi.
Pat Colgan
From Pat Colgan
Week of June 16 to June 20…
As I sit here looking out my window Friday afternoon, June 20, 2014, watching the flooding, debris filled Maquoketa River roaring by our cabin at a flow rate of 8000 cubic feet per second (cfs), I think back only to yesterday when the river was at 600 cfs and then to Monday afternoon when the the river was at 80 cfs. Average river flow for this week is 350 cfs. Depending on which day I wrote this update this week my report would be remarkably different. This week offers a vivid reminder that our river is a uniquely “flashy” river where flooding waters can occur quickly and sometimes severely.
As of last Monday, June 16, our rebuild project had just experienced 3 wee ks of excellent construction weather and low river flows which allowed significant progress in Phase 1 work. By Thursday afternoon this work progress was continuing with many significant tasks being achieved even though the river was rising rapidly. Upstream and downstream cofferdams protected the work in progress. Around 3:00 pm that day a line of storms forced work to suspend mainly due to lightening. The storm lasted for an hour or so effectively ending work for the day.
More rain Thursday evening. When I went to bed at 11:00 pm, the river was at 1000 cfs. When I got up at 4:30 am on Friday, it had increased to 4500 cfs. I went to the dam and took pictures when it was light enough, about 5:30 am.
Even though the cofferdams are sound all of the work on the upstream side and downstream side was flooded. Despite all this, the contractor Lunda, was able to work on higher ground to install some sheet piling needed to be able to excavate more material on the north upstream end of the concrete structure on Friday.
By Friday afternoon the rive flow had risen to 8000 cfs.
Barring more rain, the river flows will fall over the weekend and early next week we will be able to determine when the work areas can be pumped out and areas cleaned up to resume the great work that had occurred over the last three weeks.
So when I am asked when will the lake be ready, I wonder will we have more days like Monday, 80 cfs, or like Friday, 8000 cfs, over the next year or so? That will tell us when the project will be complete.
General Project Information
As has been discussed, the rebuild plan will be accomplished in two parts, Phase 1 and Phase 2.
Phase 1 will restore the concrete portion of the dam on the north side of the river. Phase 2 work will follow later this summer will restore the earthen dike on the south side of the river including a new large concrete labyrinth overflow spillway.
The important critical goal of Phase 1 work is to complete enough refurbishing work on the concrete structure to allow river water flow to be diverted through it from the current river bed flowing through the breeched dike area.
Current Project Progress and Status in last 10 days, June 10 to June 20, 2014
The important DNR permit allowing the entire project to be constructed including Phase 2 has been received.
Phase 2 work is now ready to be bid and awarded. The timing of the Phase 2 bidding will depend on being confident that Phase 1 work will be substantially complete by October allowing for the river to be diverted through the refurbished concrete structure. Right now in looks like Phase 2 work will be bid in July 2014 for an August 2014 contract mobilization to begin this work.
Project completion date is heavily dependent several factors including river flows being average or below (not this past week), minimal weather extremes in the next 12 months, selecting a quality contractor for Phase 2 and sufficient flow in the river at available at the time needed to refill the lake.
Specific Progress by Lunda on Phase 1 work through June 20, 2014 includes:
Work Progress from June 10, 2014, to June 20, 2014
Excavation for the Rock Anchor Block is 90% complete.
Lunda has finished assembling scaffolding and placing it on top of spillways for pier nose removal.
Lunda continues a daily vigilance of making the work site safe.
Eastern Iowa Concrete Sawing has begun sawing on existing Pier Noses for removal.
Lunda has finished preparing upstream face of dam for Rock Anchor Block by roughening the concrete wall where the Block will be in contact with it.
Lunda will continue to drill holes for rebar anchorage into face of dam at Rock Anchor Block elevation.
Lunda has poured a mud slab to level the bedrock at the ends of the upstream side of the dam.
B&J will continue pumping ground water from Stilling Basin.
Downstream Silt removal is complete.

The Combined Lake Delhi Recreational Facility and Water Quality District
Board of Trustees Meeting
Thursday, June 19, 2014 – 6:30 p.m.
Maquoketa Valley Middle School Conference Room
Delhi, IA
The meeting of the Combined Lake Delhi Recreational Facility and Water Quality District Board of Trustees was called to order by President Steve Leonard at 6:38 PM at the Heritage Bank Conference Room.
Trustees present: Leonard, Kramer, Davidson, Schneider, Gifford, Kray and Burger by phone
Trustees absent: n/a
Visitors: Ed Schmidt, Don Dede, Pat Dede, Larry Peter, Ken Kray, Sue Christiansen, Lou Christiansen, Barb DeKlotz, Ken DeKlotz, Dave Larson, Bob Galiher, Lola Galiher, Chip Hughes, Jim Locke, Jason Wenger, Carla Becker, Pat Colgan, Chloe Colgan, Dan Staebell, Clark Gochenour, Nancy Gochenour, Dan Zumbach
Agenda was reviewed by Leonard. Motion by Schneider to approve agenda, Kramer second, all ayes, motion passed.
Kray requested approval of 5/21/14 and 6/5/14 minutes. Motion by Davidson to approve, Gifford second, all ayes, motion passed.
Kramer detailed billings for the General Fund. Alliant Energy – $43.11; Kramer Lawn Care – $300.00; L&L Consulting – $2000; Simmons Perrine Moyer Bergman – $520.05. Billings for the Bond Fund are Lunda Construction – $82,210.93; Burrington Group – $4,208.01; Simmons Perrine Moyer Bergman – $641.25; Delaware County Abstract – $955.00; Delaware County Transfer (demolition of Peck Property) – $6,399.40. Kray made motion to pay billings for the General and Bond funds, Kramer second, all ayes, motion passed.
Kramer gave review of the Financial report for month ending May 31, 2014. The General Fund began with a balance of $155,193.51 and after revenues and expenses, ended with a balance of $116,862.73. The Debt Service Fund began with a balance of $355,013.70 and after revenues and expenses ended with a balance of $13,360.28. The Dam/Spillway fund started with a balance of $5,244,522.43 and after revenues and expenses, ended with a balance of $4,972,661.09. Kramer also introduced reports provided by Delaware County Auditor’s office to assist us in understanding the flow of funds from our multiple sources of monies. Motion to file financial reports by Schneider, second by Gifford, all ayes, motion passed.
Kramer discussed the submission of $531,600.70 in expenses for Phase II construction to Delaware County. According to the agreement we are allowed a 50% reimbursement. In addition,the terms and conditions of our agreement with the County allows for a one time opportunity to request funds for expenses already paid on Phase II (spillway) within 45 days of permit receipt. Carla Becker indicated the County Supervisors have amended their budget to allow for this request. These expenses have already been paid for by the bond fund but have not been reimbursed from the State. Motion to approve request of $531,600.70 to be submitted to the Delaware County Supervisors for Phase II work by Schneider, Gifford second. All ayes, motion passed.
Leonard explained that originally we appealed our property tax billing as we believed we were tax exempt. Since then, legislation was passed to confirm the District was tax exempt. This resolution indicates that we are dismissing our appeal as the legal cost to continue the appeal would be more than the tax bill itself. Motion to approve resolution 6.19.14a by Davidson, Schneider second. Individual roll call requested, all ayes, motion passed.
Kramer advised Superintendent Tuetken approached her regarding the possibility of the District using the old Maquoketa Valley Administrative Building across the street as a permanent site for the District. Kramer indicated each Trustee should view the office before a decision is made and look at the pros and cons of this site compared to the office building down by the dam. This item will be discussed again at the next regular meeting.
Burger made motion to modify Resolution 5.21.14 passed last month by the District Trustees. The original resolution indicated the method for emergency change orders, however, there was a reference to approval by email that needed to be removed. Motion was seconded by Gifford to approve Resolution 6.19.14b, individual roll call requested, all ayes, motion passed.
Jason Wenger reviewed updated specs for the Rocky Nook Waste Water Treatment bid. The changes requested by the Board now reflect a purely performance based specification that gives quantity of flow that the new system must adhere to. The bid also indicates that at a minimum of 14 days before the final submission date the contractors must submit their proposed design so the county can give conditional approval. Three days before the final submission date, an addendum will be written to indicate which systems have been approved. Kramer made motion to approve the new bid specs with a bid opening date of July 24th at 4pm at the Delaware County Courthouse and an award date of August 1 at 3pm, Schneider second. All ayes, motion passed.
Leonard explained the need for the Storage Water Permit. Since our dam is a rebuild, it was originally thought we did not need to request this permit. After investigation by the DNR, it was found that a storage permit was never signed when the dam was first constructed so the DNR is asking us to request this permit at this time. It is simply administrative and has a $75 fee. Motion to approve $75 fee and to allow the President to sign the permit request by Davidson, Gifford second, all ayes, motion passed.
Bob Galiher gave presentation regarding the Water Quality team. He read their mission statement and gave the history of the team. The team originally started as their own entity and has always been staffed by volunteers. Galiher says there are 3 concerns: this is a hypertrophic lake which means more nutrients come in than needed; sedimentation; and bacterial and chemical pollution. The team has also participated in meetings with the NRCS on watershed projects. Traditionally the Water Quality Team has granted $50 for septic pump outs and $500 for shoreline improvements and their expenses have been between $3500 to $4000/year. Their revenues were provided via grants and by payments from the LDRA which ranged from $2000 to $3500/year. The Water Quality Team’s current balance is $3268 but there are 3 approved shoreline projects that have not yet been paid as they are not completed. The members of the Water Quality Team recently met and agreed they would like the District Board to consider acting as the leadership arm of the team and the funding source. The team feels the work done is far too important and strongly feels it should continue. Gifford said that approximately 10 people took the IoWater training last summer. Lola Galiher advised that there will be training needed to continue the bacterial tests as Lou Christiansen is the only trained member of the team in this category. The current members will be there to assist but just can’t physically get to some of the locations to test. Gifford indicated that the current team holds a huge amount of knowledge and gives us a good template to start from. All agreed that water quality is necessary as we move forward and that the District will hold a work session to determine next steps and how to move forward. Leonard thanked the Water Quality Team for all they have done and thanked Bob for his presentation.
The continuation of the Lobbyist contract was on the agenda and Burger moved to table it until next month, Gifford second. All ayes, motion passed.
Leonard recognized Dan Zumbach, our Iowa Senator that was in the audience. Senator Zumbach indicated the Lake Delhi project has been successful because of all of us. The District asked for state help but only after we helped ourselves and taxed ourselves. Senator Zumbach advocated for us and received a 49-0 vote in the Senate for our funding. We are grateful to Senator Zumbach and Representative Hein for all they have accomplished for us. Leonard then asked the Senator his thoughts on the lobbyists assistance going forward. The Senator indicated that there is an election this fall and elections have consequences. He indicated he is not sure how much longer their services should be needed but we should consider their retention until the water is back and all the bills are paid.
Kramer introduced the new job description for the Recording secretary position that was agreed upon by the Finance Committee last Saturday. Kray read the job description. Davidson said the duties can be defined once the party is in place. Motion to move forward with new job description and to follow process recommended by the Finance Committee which is first to request a volunteer from the Board, then a volunteer from the Lake Delhi community and if we don’t receive a volunteer, to allow the hiring of a contract employee by Kramer, second by Kray. All ayes, motion passed.
Committee updates
Finance – Davidson wants to make sure we purchase a computer so all records aren’t on personal
computers. We will discuss this in our next work session as to what our needs are.
Dam Construction/Timeline – Colgan indicated we have had 6 weeks of work on phase I and that community members could go to lakedelhi.org for updates and construction photos. Phase I is about the concrete structure and improving the powerhouse to more modern codes. The concrete slabs under the old spillway is being inspected. The sluice gates used to divert water in 1928 were thought to be full of concrete. However today the contractor was able to shine a high intensity light through the tubes and confirm that they are not full of concrete and we should be able to use them but that will be confirmed in the next few weeks. Colgan said before we go out to bid for Phase II, 4 items need to be confirmed: 1- the sluice gates are ok; 2- the spillway floor is acceptable; 3 – the cutting of the piers to allow for new gates go as planned; 4 – the grouting of the powerhouse needs to progress satisfactorily. Lunda should be able to pass water in October so the District will most likely go out for bid on Phase II in mid July.
Colgan also wanted to reiterate that people must stay out of the construction zone on the north side of the dam. No trespassing signs will now be displayed. He also wanted to make sure that we all understand that even though Lunda Construction is from Wisconsin, the majority of the workers are from Iowa and the supplies are being purchased in Iowa.
State/County Legislature – Leonard went to last County Supervisor meeting and gave an update of the progress. Becker said the Supervisors believe we have a true partnership and we all look forward to the completion of the Turtle Creek project and the dam rebuild. Becker also reminded all of the upcoming election on July 22nd and reminded us that her office will be open for voting on July 12th. Kray said she would be sending an email blast this weekend reminding the community of the election and pertinent dates.
Property Mgt – Kramer advised the old Peck property was deconstructed.
Public comment – Nancy Gochenour asked why the District is working with septic systems at Rocky Nook property and Leonard advised as part of the agreement for the land needed there, the Rocky Nook Association requested assistance with their water treatment system.
Dave Larson asked how long to get Turtle Creek done. Leonard indicated should be 2-3 months. Becker indicated the goal is to not impede our progress.
Clark Gochenour asked if the water quality will be better with new dam. Colgan said channel is cleaned out but we will still have sediment accumulation.
Bob Galiher reminded all that our lake is a public body of water that people like to visit to boat and fish. The rebuild is not only for ourselves but for others who love Lake Delhi as well.
Larry Aschenbrenner said the DNR letter indicated that if there was any development below the dam in the future, it could change the status of our dam. Colgan said this is typical language in every dam permit and it is highly unlikely that a permit would be granted to build in a flood plain.
Chip Hughes asked what is the projected date for completion. Colgan said it is based on weather but a cautious estimate is July 4, 2014.
Jim Locke said the LDRA has $22,000 for the rebuild effort. He will work with Kramer to determine how that money can be used.
Bob Galiher said people are putting in big sea walls and putting rip rap out in front of them so waves are broken up. He feels the District should put a recommendation in our newsletter that the rip rap is needed to preserve the walls. Gifford said the DNR has documentation that explains it and he will add it in the next Voice.
Motion to adjourn by Davidson, Schneider second. All ayes, motion passed. Meeting adjourned at 8:48 pm.

Delhi Dam Construction Progress Report #2
June 10, 2014
General Project Information
As discussed last time, the plan to rebuild Lake Delhi dam and restore the lake to its former lake level will be accomplished in two parts which have been called Phase 1 and Phase 2.
First, Phase 1 will restore the concrete portion of the dam on the north side of the river. Finally, Phase 2 work will follow later this summer will restore the earthen dike on the south side of the river including a new large concrete labyrinth overflow spillway.
Phase 1 was awarded to Lunda Construction Company, a large and experienced heavy structural midwest firm from Wisconsin in April 2014.
The important critical goal of Phase 1 work is to complete enough refurbishing work on the concrete structure to allow river water flow to be diverted through it from the current river bed flowing through the breeched dike area.
Current Project Progress and Status in last 10 days, June 1 to June 10, 2014
The important DNR permit allowing the entire project to be constructed including Phase 2 has been received late last week. This is great news for the project.
Phase 2 work is now ready to be bid and awarded which will lead to the completion of the dam rebuild project. The timing of the Phase 2 bidding will depend on being confident that Phase 1 work will be substantially complete by October allowing for the river to be diverted through the refurbished concrete structure. Right now in looks like Phase 2 work will be bid in July 2014 for an August 2014 contract mobilization to begin this work.
Project completion date is heavily dependent several factors including river flows being average or below, no weather extremes in the next 12 months, selecting a quality contractor for Phase 2 equivalent to our Phase 1 contractor and the actual flow in the river at the time needed to refill the lake.
Right now for planning purposes, we are planning for a July 4, 2015, date to resume enjoyment of Lake Delhi. it could be sooner if everything listed above goes great.
Specific Progress by Lunda on Phase 1 work through June 10, 2014 includes:
Work Progress from June 1, 2014, to June 10, 2014
Lunda finished installing scaffold in all spillways so subcontractor, EICS, from Farley, Iowa, can sawcut Pier Noses for removal.
Continue removing silt and dewatering upstream and downstream. Approximately 90% of silt has been removed from downstream Stilling Basin.
Removed and disposed of all spillway concrete beams.
Excavation for upstream Rock Anchor Block is about 70% complete
Lunda has begun cleaning and roughening face of dam and drilling holes for Rock Anchor Block rebar anchorage.
