About

From Tustumena Lake to Cook Inlet, the Kasilof runs 17 miles through the Kenai Peninsula Borough at an average 1,800 CFS — substantial water that handles drift boats and jet sleds across its Class I-II gradient. The upper five miles below Tustumena Lake operate under fly-fishing-only regulations established in 1996, targeting king salmon in cleaner water before the glacial tributaries muddy the flow. The middle section from the Sterling Highway bridge to Crooked Creek covers seven miles of prime drift boat water, while the lower five miles to Cook Inlet host Alaska's dipnet fishery during summer runs. Optimal flows run 500–3,000 CFS on USGS gauge 15242000. The Dena'ina Athabascan people established salmon camps along these banks for generations before contact. Kasilof River Lodge operates guided trips through the system, which serves as both an ADF&G-managed sport fishery and a subsistence corridor for local communities.

Data Quality

River conditions are community-verified. CFS ranges, difficulty ratings, and access points may not reflect every flow level or seasonal change. Always check current conditions, scout unfamiliar rapids, and paddle within your skill level.
