I was at a wedding a couple years ago at Maine Lakeside Cabins at the very north end of the "lake". I say lake because it certainly looked like the river to me but recall someone saying that they do ice fish there. Facilities were beautiful. It could be worth checking into. A quick Google search also revealed a private rental , Cozy camp rental. Looks nice, opposite side of the lake in Pleasant Ridge, know nothing about it otherwise. Like Jim eluded to, one of the most dangerous lakes in Maine if you don't know where you are going, nothing more than a wide spot in the Kennebec. Good luck.
