1.) A concrete check dam was constructed midstream to force water into an existing intake structure. The flow from the creek had to be diverted before the concrete work could be done. In the past, a check dam was constructed out of gravel by using machinery, but these days this practice is no longer environmentally acceptable.
2.) To ensure that a good seal is achieved, all large rocks must be removed from the path of the AquaDam. In this case, the rocks were placed just downstream of where the AquaDam will lay so that the rocks would help support the dam once it was installed.
3.) A view of the intake structure that needed repairs, looking downstream.
4.) A view from the intake structure, looking upstream at the 5ft tall single closed end (SCE) AquaDam.
5.) A view from above the 5ft tall SCE AquaDam. Here we can see the starting point of the SCE AquaDam. A SCE AquaDam requires a bank to keep its starting point (open end) higher in elevation than the body of the AquaDam. The open end and fill-tubes of a SCE AquaDam must be elevated higher than the full height of dam along its given path. An AquaDam will only reach its full height at the lowest elevation along its given path.
6.) The open end and fill-tubes have been tied off to prevent them from slipping down the starting bank.
7.) Before the AquaDam was installed, the creek was only about an inch and a half deep. However, due to narrowed path of the diversion channel the water depth increased dramatically upstream, which is why a 5ft tall AquaDam was used.
8.) 20 Mil vinyl was used to line the diversion channel to prevent the high flow rate from scouring away the banks.
9.) A close-up view that displays the AquaDams' inherent flexibility. The sandbag was used to plug a seepage hole.
10.) A view of the rock berm on the downstream side of the 5ft tall SCE AquaDam.
11.) A view of the upstream pool of water that was created behind the 5ft tall AquaDam. It is important to know that water will pool upstream of any cofferdam in flowing water.
12.) Great job AquaDam!
