Susan,

Planting large canopy, native trees would be best to reduce stormwater runoff and reducing soil erosion that impacts the lake's water quality.   Although fruit trees might provide something edible, they are quite a bit of work and require a spray program to prevent diseases and insects that affect the fruit (also lots of pruning needed).   If you choose to go with fruit trees, try some new disease resistant varieties of apple.

The American Chestnut Foundation www.patacf.org/ does provide some new disease resistant trees to its members, but does not have any for sale as of yet.   If you are a member, you can contact our national office at<personal data hidden> to find out where they are in that process.

Aside from Fruit Trees and American Chestnuts, you should consider large native trees such as white pine, red and white oak, swamp white oak, red maple, blackgum, tuliptree (yellow poplar), white spruce, and American linden to name a few.   It is best to evaluate your site and plant in the spring (April).   If you are using seedlings to replant, tree shelters (Tubex) are critical to keep deer from browsing the young trees. Five foot tree shelters (tubes) are best.

Hope this is helpful. Also visit www.extension.psu.edu for more information about replanting trees.
