The Reservoir is about 5 acres in area, and has no public access nor any facilities of any type nearby. I believe there may be a few catfish in the lake, but not much else. In the summer, the size of the lake is reduced to about half its maximum spring size. Further, the reservoir is not near the wallowa mountains, which are not even in Idaho. Says Ed Nunnallee
If you need a place to stay Americas Best Value Inn Ontario is a wonderful choice, and not far
from Barton Reservoir you obtain some delightful water scenery at Barton Dam. You assume that's sufficient? Just getting warmed up. A journey to Barton Reservoir wouldn’t be complete without a trip to close by Ontario State Park.
