Progress Is Being Made, City Lake is being filled !
The City has reached substantial completion on the dam and authorized to begin filling City Lake.
Filling began on Thursday October 10th at 1:00 pm. at a rate of approximately 4 acre feet per day.
The City will be utilizing our direct flow rights as well as drawing down Wahatoya and Daigre reservoirs as necessary.
Construction crews are wrapping up with cleanup and installing fencing.
The City of Walsenburg has been dilegently pursuing the City Lake Dam Construction Project for several years to meet State of Colorado requirements and provide additional storage.
Financing has been obtained and sealed bids were opened November 7, 2018 with the contract awarded to the lowest bidder - Kirkland Construction, Rye Colorado (subject to approval by Council on November 20th).
After a contract has been approved by City Council (November 20, 2018 meeting) and signed, the City will completely drain the reservoir and begin drawing water from Horseshoe Reservoir for treatment at the City Water Treatment Plant.
Construction Management Consultant - RJH Engineering
On December 18, 2018 City Council approved a Professional Services Agreement with our consultant RJH Engineering to provide engineering observation, field engineering, and materials testing on site.
Kirkland Construction is also on site and the Dam Reconstruction Project is underway!
Once these steps are complete the dam will be rebuilt, a new intake for the treatment plant will be installed and the dam will be refilled.
The Dam embankment rises daily.
The top of the embankment shown here is five feet short of the finished elevation.
It will be encased in concrete and will conduct water from the reservoir to the Water Treatment Plant.
Very impressive progress is being made on the City Lake Dam project. On schedule and on budget.
The Rip-Rap is an assembly of three layers. Coarse gravel, small stones and basalt boulders. Rip-Rap stabilizes the earth embankment against erosion by wind and waves.
The concrete foundations provide support for the outlet gates and the spillway.
The crane pump arrived to pour the second lift at the spillway,
To ensure quality control slump tests are taken. Techs test weight and air content and take sample midway in the pour,
Progress is being made on the spillway with the main feed to the treatment plant installed and welded, forms set and poured and the spillway cast,
Crews are busy laying riprap near the spillway and the forms have been removed from the headworks. The project is on schedule for substantial completion in mid October.
The Headworks are complete. Finish grading on the dam face is wrapping up. The reservoir basin and outlet are looking good. Compaction testing on the roadway is being done as the roadway nears completion. The City Lake Dam project is approaching substantial completion and the City anticipates beginning to fill the reservoir in mid-October.
