They must have improved the ramp since I lived out there. There was a dropoff of a couple of feet when the water was low in winter and early spring. There was no way that a boat the size of yours could have gotten in and out.
Donner is a beautiful lake for sure. I always had trouble getting the macks to hit anything there. I could see them come up off the bottom to look a plug or a flasher only to turn away and go back down. Always did better at Stampede and Tahoe.
Can you tell me what they were hitting? I used spoons, flatfish, and Lymans and only got a few macks over the years. Some years there were a lot of kokanee in August, but most years they were small.
