This is one of my favorite water areas here in Idaho. Easiest way to get there is by horse back. The scenery is great. In the spring of the year you might see wild mountain sheep on the mountain sides. You are assured to see at least one moose eating knee deep in the lake. Fishing is Okay if you dare to venture that far in to the waters edge. The lake along with the one that is high up the trail was made my the side of the mountain sliding of and damming off the creeks natural flow. The water is deep and clear blue/green. The trail is heavily used as the in one of the areas favorite foot hiking trails. As for me I prefer the back of my trusty steed.
Easter Idaho is just full of places like this, some not so well used and a bit more hidden.
