This relatively deep lake is primarily managed for rainbow trout and kokanee but support naturally reproducing largemouth bass, smallmouth bass, yellow perch, brown bullhead, pumpkinseed sunfish, coastal cutthroat and northern pike minnow. Many anglers find success targeting rainbow trout in April and May then kokanee, yellow perch, and bass in the summer and fall months. Public access to the lake is available via the WDFW owned ramp located on the southwest end of the lake. Features of the access include a two-lane boat ramp, restrooms, and about 50 (15 for vehicles with trailers) vehicle parking stalls. The boat launch is in fair condition and doesn’t include a launching dock. Shore fishing is limited to small areas on each side of the ramp and can be difficult when boat anglers are abundant. Additionally, the area within 100 yards of the shore is very shallow which limit shore fishing success. Anglers who target rainbow trout are successful either still fishing with bait or trolling with a combination of bait and or lure/fly. Angler who target kokanee report finding success while fishing with downriggers or leaded line with wedding rings, small squid, spoon, all tipped with corn or maggots. Rainbow can be found throughout the lake but anglers should target kokanee in the deeper portions of the lake. Kokanee are typically found at variable depths depending on water temperatures so anglers will need to experiment when targeting these fish. Overall Summit Lake is one of the most popular fisheries in South Puget Sound.
