Grant Lake Marina and Campground, no phone. Marina and boat ramp open only to long term guests in the campground. There are a few shoreline locations where a boat may be launched. Like June Lake best fishing here is early, early trolling 4 to 5 colors lead core if not deeper for Oregon Rainbows and resident Browns, Cutts, and occasional Kamloops or Cut-bows. On weekends the upper portion of Grant above the narrows has been nearly wall to wall with RVs and extreme water toy activity. No sense fishing here the weekends so stick to mid-week. Boat, tube, or kayak targeting the submerged Rush Creek channel. Use that drifting with the wind method mentioned above. Dan of Dan’s Guide Service, 661)478-0036, who fishes mainly that upper section in the evenings says its been slow on weekends and better during the week. Give you one guess why.
