Agency Lake Fishing Guides
The shallow northern basin of the Upper Klamath system, fed by spring-fed rivers and holding the same enormous Klamath redband trout with far fewer boats on it.

About the Agency Lake
Agency Lake is the northern basin of the Upper Klamath Lake system, joined to the main lake by a narrow channel at its southern end and fed from the north by the Wood River and from the east by the Williamson. It is shallow even by the standards of this famously shallow basin, and in a dry year parts of it become barely navigable. What it has going for it is the same thing the main lake has: an extraordinarily productive food base that grows native Klamath redband rainbow trout to sizes found almost nowhere else in Oregon, with the added advantage that far fewer boats bother with it.
The fishing follows the same thermal logic as the main lake. Through the cool months trout are spread through the basin, and as summer arrives and the algal bloom builds, the fish concentrate near cold inflows, most importantly the Wood River delta at the north end and the spring-fed water along the western shore. Anglers work leeches, dragonfly nymphs and streamers along the weed edges and the old river channels from drift boats, prams and kayaks, and the reward is a small number of very large fish rather than a busy day. Brown trout appear occasionally, largemouth bass and yellow perch hold in the warmer shallows, and the basin’s non-game fish include the endangered suckers that drive the Klamath Basin’s water politics.
The gauge near Klamath Agency reports lake elevation and nothing else, and on a basin this shallow that is the number that decides whether a trip happens at all. A foot of elevation change moves a great deal of shoreline here, opens or closes the channel to the main lake, and determines whether the Wood River delta is reachable by boat. Read the trace and the trend rather than a single value, and pair it with the season: late spring and early summer, before the bloom takes hold, are the best weeks of the year on this basin.

Access
Klamath Agency - the gauge community at the northern end of the basin.
Wood River delta - the spring-fed northern inflow and the principal cold-water concentration.
Williamson River mouth - the eastern inflow, shared with the main lake and a major migration route.
Agency Lake Resort - the long-standing launch and lodging on the western shore.
Upper Klamath Lake - the larger basin south, connected by channel and holding the same fish.
Chiloquin - the nearest town, with groceries, fuel and access to the Williamson.
Klamath Falls - the regional city south, with lodging, tackle and guide services.
Seasons
Spring: the best weeks of the year, with cool water, no bloom and large redbands spread through the shallow basin.
Summer: the bloom concentrates trout hard at the Wood River delta and the western springs, where the fishing can be exceptional.
Fall: the bloom breaks down and fish spread out again, with good fishing and almost no other boats through October.
Winter: cold, frequently ice-affected and very lightly fished, with access the limiting factor rather than the fish.
