Fishing prospects calendar

Coastal cutthroat trout (resident)

Fishing is best for Coastal Cutthroat in the spring and fall. There is a summer lull as fish move offshore into deeper waters to escape the summer heat in July and August. Catch is lowest in the late-winter while adults are spawning in tributary streams.

Largemouth bass

Fishing improves throughout the spring as waters warm and fish move onshore, peaking during the spawn. Summer is a slight lull though dawn/dusk hours can be very good. Catch improves in Fall as waters cool, vegetation begins to die back, and prey becomes more available. Winter is the hardest time because fish are offshore and slow moving.

Yellow perch

Yellow Perch can be caught year-round. Fishing is best in the summer after they finish spawning in April-May. Fish can be readily angled through the summer from both the shore and boat. Catch begins to decline in the fall as water temperatures cool and fish move offshore forcing anglers to pursue them in boats. Successful fishing for Yellow Perch in the winter involves either targeting schools in deep water from boats or through the ice.

Black crappie

Fishing improves throughout the Spring, peaking during the spawn. Summer is a slight lull, while Fall sees an improvement as waters cool, vegetation dies back, and prey becomes more available. During winter, the bite is slower, but anglers can have great success fishing through the ice when conditions are safe.

Pumpkinseed Sunfish

Pumpkinseed Sunfish are ubiquitous in most lowland lakes and readily caught year-round. Fishing is best in the spring and summer, peaking during the spawn in June. Fish move offshore into deeper waters through the fall as water temperatures cool making it more difficult to target them. Winter is the most difficult season to catch Pumpkinseed, but persistent anglers can find nice-sized schools offshore.

Brown bullhead

Fishing improves throughout the spring, peaking before the spawning period in May and June. Fishing may pick up in early Fall, followed by a decrease in action as waters cool. Winter is a difficult time to target this species.
