Roche
Have fished Roche many times, usually twice a year. Roche is generally a great interior lake. It tough to fish from belly boat, because you limit you range. Boat is way better, you will need an anchor. A car is just fine to get to the resort, but if you want to try any of the surrounding lakes a 4x4 is definetely reccommended
Fishing the South end of the lake I find is best (to the left of the resort is best) in and around Monster bay & the area just before Carl's Flats (the no motor area) at the back.
Choronimids (bead head) for sure this time of year till mid June and be patient. Wind can pick up quick and make it difficult to fish so find a cove or bay that is sheltered.
I prefer to camp on the West side of the lake (Forestry West Camping Area) as it is closer to the area's I like to fish. Also just a short boat ride to the Resort for fresh ice. Got to keep the beer cold!!!!

Check out the link to the resort web-site it has maps. Click on the Photo's tab and it has maps of Roche Lake and all the surrounding lakes and side roads.
Good Luck,
