Rainbow trout were stocked last week. Only boats with a single electric motor are allowed on Knoll Lake. No gas-powered motors. The limit is 4 trout. Trout were caught over the weekend on worms and PowerBait. For fly anglers, the cicadas are starting to appear within the watershed; a dry and dropper combo may be worth trying with a prince nymph, pheasant tail, or black Simi-seal leech as your bottom fly.
