Stream Diversion
Phase One
Antelope Creek
Lincoln, CA (2000)

Now that the original channel is nearly blocked off, most of the water is flowing down the diversion channel. What water does get through has a great amount of velocity. The bank is only 3' away, but the crew must stop, hold the AquaDam® in place and wait for head pressure to build back up.

You must be careful as the last workers legs are removed and the AquaDam® extends to the bank. Notice that a boil has already developed underneath the AquaDam® due to a silted-in tire. This was later controlled by extending a piece of polyethylene sheeting across the front of the AquaDam®.

The AquaDam® abuts into the bank. The unrolled portion is kept high enough up the bank to make sure it will not be trapped by the inflated AquaDam®. Phase One is now complete. The water flow has been entirely diverted around the work area by the diversion channel.
