Rainbow Trout species guide

Lake Sylvia offers good spring, early summer and fall fishing for 9- to 10-inch Rainbow Trout, with larger rainbows and some resident Coastal Cutthroat Trout also available. Jumbo Rainbow Trout that average 4-6 pounds each are also planted, with the first fish stocking typically occurring in mid to late March. The state park provides good shoreline access along picnic and campground areas plus along the boardwalk and bridge crossings, and anglers can cast a line from the fishing bridge in summer.
