1980s
Increasing interest in riparian communities and
value as fish and wildlife habitat
Concern increased about
sand and gravel mining
in the Verde River channel
![Page 3: Approaches to Address Riparian Issues in Arizona...Approaches to Address Riparian Issues in Arizona The 1980s, 1990s, and the New Century W. E. Werner Environmental Program Manager](https://reader036.fdocuments.in/reader036/viewer/2022080720/5f799c2ce33541506266f480/html5/thumbnails/3.jpg)
Verde River Sand and Gravel
Sand and gravel mines were working the channel
of the Verde River
Channelization was conducted to move water out of
active excavation
Riparian habitat removed in the path of excavation
Headcuts and channel changes impacted riparian
habitat

streambed under the Equal Footing Doctrine
