An Environmental Assessment (EA) was released to the public in June, 2013, for a 30-day review and comment period. Over fifty comments were received, with most in support of Alternative 2, the preferred Alternative.
The Comprehensive Fisheries Management Plan was developed in coordination with the Arizona Game and Fish Department and U.S. Fish and Wildlife Service. Alternative 2 of the EA was approved in the FONSI, which will be implemented over the next 20 years, and includes:
· Fisheries management goals and objectives for specific waters within both NPS units;
· A comprehensive “toolbox” of fisheries management techniques, such as:
Ø Stocking of sterile (non-spawning) rainbow trout in Lees Ferry in the event the fishery declines;
Ø Translocations (i.e., moving fish from one location to another) of native fish species, including endangered humpback chub;
Ø Removing high risk nonnative fish from selected areas that are important for native fish, including through targeted volunteer angler-facilitated river trips in Marble Canyon, and comprehensive mechanical trout control in and near Bright Angel Creek;
Ø Beneficial use of all nonnative fish removed;
Ø An experimental adaptive strategy for evaluating razorback sucker habitat suitability in the western portions of Grand Canyon.
The NPS will begin implementing the actions included in the FONSI, effective immediately.
