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.
