There aren't any other launches on the Lamoille, but you can motor upstream quite a ways to a couple hundred yards below Peterson's Dam. Walleye hold in that upper section quite often early in the season and can be caught in the section from the Rt2 bridge to the lake as they drop back after spawning. Not sure if there are still walleye in there or not, though. It's kind of a short-lived season. There should still be walleye in the Winooski River, if you want to travel a little further south.
