Delintment Lake is a hidden gem in the Malheur National Forest outside of Burns, Oregon. Along the way, you might want to stop at Yellowjacket Reservoir as well. It was late summer when I visited and the thunder and lightening storms were rampant. A beautiful lake for canoeing and camping; I would have to list it in my top 20 for Oregon. So far, it is my favorite lake in Eastern Oregon. The lake is surrounded by large old Ponderosa. There is a great campground, potable water and newer vault bathrooms. There is a boat launch and when we were there, the campground only had one other person in it. There are amazing campsites right on the lake.
These directions were listed on the Forest Service Website, but I would have a map in hand. Directions: North of Burns on County Road 127 to Forest Road #41. Left on Forest Road #41 for 45 miles to junction, turn left and follow signs for 5 miles to campground.
*Never Canoe during a lightening storm. We waited until the morning with a clear sky to go out on the lake.
