To protect fish habitat along a side channel of the Eel River, a channel had to be constructed through 200' of dry gravel bar and 100' out into the river. To isolate the work area, three 1' x 100' AquaDams® were placed in a crescent shape out into the wide and shallow Eel River. Notice the brown contained water.

A canal had to be dug out into the middle of the river so that an adequate flow of water could reach the side channel. To isolate the work area, the AquaDams® extended far out into the shallow, flowing river. The 300' of AquaDams® took approximately 2 hours to install.

To get the needed flow, a large mouth had to be excavated at the end of the channel. The dirty water caused by the excavation was totally isolated from the river.

AquaDams® can be turned to form virtually any configuration.

A view of the other end of the channel, where it intersects the side channel with a large fish population. Upstream, the channel will need to be blocked off for construction purposes. This will isolate over a mile of stream channel, causing it to dry up. A water channel had to be dug to supply this stretch of river with the needed water.
