Hi Greg,
There is a noise law in Idaho. It really sucks because it was more designed to keep the jet boats out of Hells Canyon. The rafters got upset with them. But the law is for all waterways.
My two brothers and I have v-drives. We run our boats on Lucky Peak just east of Boise by about ten miles. When you say north of Boise does that mean Cascade or McCAll? There is two lakes on those towns. One is deep and built up like Tahoe years ago. The other is shallow and big. Both are pretty good lakes until the wind comes up. Let me know where your moving to and I can help more.
