Anglers harvesting large rainbow trout at Diamond Lake can help improve the fishery.
A release from the Oregon Department of Fish and Wildlife said anglers are asked to provide scale samples to help inform future fish stocking. Through Labor Day, the department will collect scale samples from harvested rainbow trout over 20 inches.
Megan Dugan from ODFW said Diamond Lake is managed as a high-yield fishery and scale samples will be used to show age structure of rainbow trout in the lake. Dugan said combined with fish health condition, water quality factors and more, this data will help biologists maintain a quality fishery and help inform potential future management decisions.
ODFW is requesting scale samples from harvested rainbow trout longer than 20 inches along with length measured from the snout to the center of the fork in the tail. Instructions and envelopes for the sample and information are at Diamond Lake Marina.
Dugan said angling at Diamond Lake is good. Both the north and south boat ramps are open but Diamond Lake campgrounds remain closed.
