I live a half mile from stumpfield and have had pretty good catches of bass, pickerel and crappie there. With all the snow/slush it is a mess right now though. A foot of snow covering 8" of slush...not the best fishing conditions. There have been a couple groups of people fishing near the bridge and by the canoe launch though.
The Army Corps of Engineers have signs posted all around the pond warning people about the presence of Blue-Green Algea in there. Not sure what the cold does to this algea, if it kills it or not...so I would not keep anything I caught out of it right now.
