North Twin Lake fishing extended until Nov. 9
Anglers will have an additional three weeks to enjoy fall fishing at North Twin Lake near Bend. The lake was scheduled to close to all fishing on Oct. 19 so it could be chemically treated to remove illegally introduced brown bullhead.
According to Erik Moberly, ODFW fish biologist, the treatment is being pushed back because delivery of the chemical needed (called rotenone) has been delayed.
Anglers can continue fishing under the temporary regulations adopted in October: no daily bag or possession limits, no size limits and anglers may harvest fish by hand, dip net and angling.
The temporary regulations will now be in effect until 12:01 a.m., Nov. 9, when North Twin Lake will close to all fishing during chemical treatment. The lake will re-open on Jan. 1 and will be re-stocked with hatchery rainbow trout in the spring.
Anglers and other members of the public who have questions or concerns about this project can contact Erik Moberly, ODFW fish biologist, at Erik.R.Moberly@state.or.us or at (541) 388-6145 .
Rotenone is often used to remove undesirable fish species because it is an affordable and effective treatment with little threat of long-term environmental damage, officials said.
Rotenone has been approved as a fish toxicant by the Environmental Protection Agency. At the concentrations used to kill fish, rotenone is not toxic to humans, other mammals or birds. It breaks down completely in the environment and will not be detectable within weeks of treatment, the agency said.
