Thanks for this fine report. It's been a few years since I've been to Virginia lakes. We used to camp at Trumbull and fish it and both Little and Big Virginia as well as the higher lakes in the Hoover wilderness. My favorite fly there is the green and olive matuka.
My first float tube experience in the sierras was in a belly boat in little Virginia. We have rented boats there and had fun. I've caught Alpers, rainbow, browns and brookies in and around there, then a short hike into the wilderness has brought goldens to hand. Great place. Now I gotta go there again. Jim
