We've got a cabin on the lake on the east side. They drop the water level every fall and start bringing it back up in the spring. Sometimes it's not til Memorial Day weekend that it gets filled up. Also depends on snow fall whether it gets filled completely. There's been a couple years that our dock hasn't been in the water the last fifteen years. Great Lake for Kokanee, burbot and trout. State record brown was caught out of Sullivan in 1965 at 22lbs. Biggest the family has caught was 7 lbs.
