Ramjet, yes, the way I read the rule, anchoring for any reason, including fishing, is prohibited within 150' of shore. But remember this rule only applies to the "No Rafting Zones". On the rest of the lake you can anchor as close to shore as you want.
Crownline_guy, I read it the same way you do.
Just to be accurate, it's a rule not a statute. I only bring this up because the No Rafting Zone statute RSA 270:44. Does not have the 150' from shore anchoring rule.
