Open year-round. Agency Lake is almost completely frozen with a tiny amount of open water at the Wood River confluence. This is not an ice fishing destination. Henzel and Petric boat ramps are frozen. The dock has been taken out at both. Redband trout are moving around with many now returning to the main lake after spawning.

Catch rates remain low due to record setting drought in 2020 through 2022, resulting in poor survival of juvenile redband trout and subsequent recruitment into the adult population.

Agency Lake regulations are catch-and-release for redband/rainbow trout with no bait allowed (artificial flies and lures only). The boundary of Agency Lake is the south end of the Straits. This change is due to record low spawning escapement for trophy redband trout throughout the Klamath Basin in 2020. ODFW also encourages the use of single barbless hooks in this fishery, not removing the fish from the water, and using catch-and-release rubber nets.

Keep on the lookout for radio tagged redband trout. These fish must be released unharmed. The long antenna looks like fishing line coming from the abdomen. Please report any radio tagged fish.
