Dalton Lake

Located about five miles northeast of Ice Harbor Dam, on the north side of the Snake River, this body of water has a year-round open season. This narrow lake is planted in late winter and spring with catchable-size Rainbow Trout and is also planted with larger triploid Rainbow trout in April. Trout fishing is good but short-lived with few trout caught after June 1. Largemouth Bass, Smallmouth Bass, Yellow Perch, Black Crappie and bullhead catfish are also present.

Public access including a boat launch is provided by the Army Corps of Engineers and is located at the end of Herman Road, off the Pasco-Kahlotus Road.

Fishing prospects calendar

Rainbow trout

Fishing success for Rainbow Trout is generally best in the spring when thousands of fish are stocked statewide, but they can be caught year-round in most waters with a little patience and persistence. Success remains high into June and gradually declines as water temperatures increase and fish move offshore to stay cool. Fish that escaped the spring harvest return to the nearshore areas in the fall as waters cool off. Some waters may also be stocked again in the fall further boosting catch rates.

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.

Channel catfish

Fishing improves throughout the spring, peaking before the spawning period in June and July. 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.
