Game and Fish seeks input on chemical treatment to remove spawning suckers in High Savery tributaries fish image for chemical treatment

GREEN RIVER--The Wyoming Game and Fish Department is seeking public input on a proposal to chemically treat short reaches of the tributaries that fill High Savery Reservoir using Rotenone.

Rotenone is a naturally occurring chemical obtained from the roots of several tropical and subtropical plant species. It is a selective, non-specific insecticide, used in home gardens for insect control, for lice and tick control on pets, and for fish eradications as part of water body management.

“The proposal is to use Rotenone to kill spawning white suckers within the first half mile of stream on each tributary immediately upstream from High Savery Reservoir,” said Green River Fisheries Supervisor Robert Keith. “The Rotenone will be detoxified with potassium permanganate prior to entering High Savery Reservoir.”

“The white sucker population in High Savery Reservoir has been growing since the reservoir first started filling in 2004,” Keith said. “The suckers are now abundant enough that they are competing with the stocked trout and kokanee salmon for food resources in the reservoir. Large numbers of adult white suckers migrate out of High Savery Reservoir each spring and spawn a short distance above the reservoir in each of the three streams that fill High Savery Reservoir.”

The proposal is to chemically treat approximately a half mile of each tributary when the white suckers are congregated to spawn. The goal of the project is to reduce the number of white suckers in the reservoir and improving the sport fishing opportunities for anglers.

“During the evening of May 4th in Rawlins and May 5th in Baggs, Game and Fish personnel will provide a short presentation on the proposed chemical treatments and ask for comments and feedback on the proposal,” Keith said. “We will be at the Jefferies Center in Rawlins from 8 pm to 9 pm on May 4 and at the Valley Community Center in Baggs from 8 pm to 9 pm on May 5th to discuss the proposal. The chemical treatment meetings will immediately follow the already scheduled 2017 fishing regulation meetings scheduled from 6 pm to 8 pm on the same dates and at the same locations.”

Meetings will be held at the following times and locations:

8:00 – 9:00 p.m., May 4, Rawlins, Jeffrey Memorial Community Center, 315 W Pine Street

8:00 – 9:00 p.m., May 5, Baggs, Valley Community Center, 255 West Osborne

my only concern is the sustained population of tiger trout. will they be affected?
