Lake Overview:

Sylvia Lake (32 acres): Located approximately one mile north of Montesano, this body of water has a year-round fishing season. Good spring, early summer and fall fishing for 9- to 10-inch rainbow trout, with larger rainbows and resident cutthroat available. The first fish stocking typically occurs in mid to late March. This popular lake receives additional trout for Free Fishing Weekend (in June, 2008 - dates are the 7th and 8th), and plants in April, May and September. This year it is scheduled for a bonus plant of 121 larger triploid rainbows that average 1.5 to 2 pounds each in April/May. Additionally, “quality trout” reared through a cooperative project with Elma Game Club and WDFW that average 4-6 pounds each are also planted in the lake. Some of these rainbow trout selectively reared and planted weigh more than 10 pounds each. If you are lucky enough to hook one, and can land it, these are very large beautiful rainbows. Surplus adult hatchery steelhead may periodically be available also and are placed into this body of water to add to the potential excitement. These steelhead count as part of the daily trout limit, and a catch record card is not required to take them. There is good access through a state park(See Washington State Parks website: for ADA accessibility information). Source: WDFW 2008 Fishing Prospects
