Kerwin Lake Fishing in Okanogan County, Washington

• Overview

  Kerwin Lake sits in Okanogan County, out in Washington. The surroundings are pine and birch. It covers about 11 acres, so this is small water you can walk round in under an hour. The town to know is Oroville, 13 miles out. After that come Osoyoos at 14 miles and Oliver at 23 miles. This one sits near enough to a boundary to be worth checking.

• Where to Fish on Kerwin Lake

  Nothing in our records gives a depth for this one. A natural lake fishes on cover, and cover here means weed and timber. The shallow end warms first and pulls fish in ahead of the rest. Fish documented in Okanogan County include rainbow trout, largemouth bass and sockeye salmon. Several of these carry legal protection or closed seasons; the rulebook comes before the rod. Anyone new to Kerwin Lake should walk it once before setting up.

• Seasonal Patterns

  August runs about 62°F on average, January about 19°F. The freeze arrives properly here and holds. Hard cover is dependable here; it goes around early April. The lid tends to go about early April and return around late November. The first weeks of open water and the last are the ones to plan for. Kerwin Lake runs to that rhythm year in and year out.

• Tackle & Baits

  Access is not recorded for this water. Nothing is mapped in the way of a ramp or car park within a short radius. For the bass here, soft plastics worked slow along cover and a spinnerbait for searching do most of the work. Read any posted signs at the access point rather than assuming. Some stretches are reserved and marked as such on the ground. Failing this one, try Lindberg Lake, 0.9 miles away. Signs at Kerwin Lake carry more weight than any list.
