Abstract

Conservation and recovery activities for native fishes in the lower Colorado River basin continued in 2010. In this presentation I will provide a short summary of activities that occurred in each 10-digit Hydrological Unit Code. Main activities focused on some of the larger recovery programs such as the Lower Colorado River Multi-Species Conservation Program, Central Arizona Project Recovery Program, and other cooperative efforts including the Stillman Lake renovation project, the Muleshoe Ecosystem Conservation program, and an American Recovery and Reinvestment Act-funded project to restore Gila trout to several streams in Arizona. Highlights for the year included the documentation of the continued recruitment of razorback sucker in Lake Mead, the translocation of humpback chub into new locations in the Grand Canyon, continued stockings of spikedace and loach minnow into Fossil Creek and other streams, and stocking of Gila trout into two new recovery areas in Arizona. Contributors include Michael Pillow (USFWS), Jeff Sorensen (AGFD), Emily Omana (NPS), Ron Kegerries (Bio-West), Zachary Shattuck (Bio-West), Mary Richardson (USFWS), Doug Duncan (USFWS), Heidi Blasius (BLM), Tim Grosch (AGFD), and Kelly Meyer (AGFD).
