Lemhi River, ID
Page 9 of 10
The AquaDam® is now fully installed, and the flow has been
increased drastically. The dry riffle has become a fish-passable
stream. Notice all of the rocks forming the pool; they were all
picked out of the path of the AquaDam® during installation.
Please note that the water on the right side of the AquaDam® is not
due to leakage. The picture was taken shortly after installation and
water had not had time to run off.
This overall view of the installation makes the difference in flow rate
obvious. Only an hour before this stream was completely impassable to
migrating adult salmon trying to return to their spawning grounds.
