LAKEVIEW, Ore. – The Oregon Department of Fish and Wildlife will host public meetings in Lakeview and Klamath Falls on Sept. 10 and 12 to outline plans to remove tui chub from Lofton Reservoir in order to improve the trout fishery.
The Sept. 10 meeting in Lakeview will begin at 7 p.m. at the AD Hay Elementary School at 500 S I St.
The Sept. 12 meeting in Klamath Falls will begin at 7 p.m. at the OSU Extension Office at 3328 Vandenberg Rd.
At both meetings, ODFW staff will describe plans to treat Lofton Reservoir and nearby Lofton Lake with rotenone in October in order to remove tui chub that are having a negative impact on the trout fishery. Staff also will go over possible changes to post-treatment trout stocking programs and answer any questions from the public.
According to Dave Banks, ODFW fish biologist in Lakeview, a recent creel survey in 2011 showed that fingerling trout stocked in 2009 and 2010 had not survived. It appears the small fish could not put on enough weight to survive the winter, primarily due to competition from tui chub for food. In recent years the agency has stocked an increasing number of legal and trophy-sized fish in order to provide a quality fishery.
“We want to try to use our hatchery resources more efficiently,” Banks said. “Fingerling trout are an economical way to stock trout, especially in a productive water body like Lofton.” By removing the tui chub, Banks hopes the fingerling fish will have a better chance to reach legal-size.
The department chose to treat the lake with rotenone because it is an affordable and effective way to remove unwanted fish with little threat of long-term ecological damage.
Rotenone, a plant substance, has been approved as a fish toxicant by the Environmental Protection Agency. At the concentrations used to kill fish, rotenone is not toxic to human, other mammals or birds. It breaks down completely in the environment and will not be detectable within weeks of treatment.
