Check out the video of Arizona Game and Fish Department installing fish habitat at Roosevelt Lake.
So far we have installed 168 fish habitat structures. During first week of October, we are having a huge volunteer effort to install more habitat at Roosevelt Lake. We have more than 400 structures to assemble and deploy. If you are interested in helping, email akjones@azgfd.gov.
