Proposed Changes to Fisheries Management Plan in Grand Canyon and Glen Canyon

Comment Deadline: June 10, 2013

The National Park Service (NPS) has released a Comprehensive Fisheries Management Plan Environmental Assessment (EA) for waters in Grand Canyon National Park and Glen Canyon National Recreation Area in Utah and Arizona. The plan is aimed at protecting endangered species such as the razorback sucker and the humpback chub, which are native to the Grand Canyon’s downstream ecosystem. Another goal of the plan is to maintain a recreational rainbow trout fishery downstream of Glen Canyon Dam, which plays a major role in the local economy and community.


The EA outlines three possible alternatives for management of these waters based in part on public comments it received in the past year. The first in a No Action Alternative. Under this alternative, the current management plan—which is not meeting the goals and objectives for fisheries in the region—would remain in place.


The NPS-preferred alternative would put in place conservation measures for endangered fish species in the Grand Canyon, such as native fish translocation, non-native fish control, and research. This alternative also includes conservation measures for the operation of Glen Canyon Dam, including the possibility of stocking sterile rainbow trout in the area to promote fishery activity.


The other Action Alternative involves more aggressive non-native fish control and fisheries management in order to meet the goals and objectives for fisheries in the region.


None of the three alternatives have been projected to have more than a moderate impact on the environment.
