Page, AZ – The National Park Service (NPS) is seeking public comment on an Expanded Non-native Aquatic Species Management Plan and Environmental Assessment in Glen Canyon National Recreation Area (Glen Canyon NRA) and Grand Canyon National Park below the Glen Canyon Dam. Public comments will be accepted for a 30-day period from Sept. 11 to Oct. 11, 2018.

Control measures for non-native aquatic species are necessary due to the increase of green sunfish and brown trout and the potential for other harmful non-native aquatic species that threaten downstream native aquatic species, some of which are listed as threatened and endangered. These non-native species have become an increasing threat since the NPS completed the 2013 NPS Comprehensive Fish Management Plan and the 2016 Long-Term Experimental and Management Plan.

To assist the public in understanding the proposed action and providing comments, the NPS is hosting various meetings to present information on the plan. Those meetings include:
