Idlewild sits in the Bull River watershed, covering surface area not recorded.

For an angler judging whether the fishing is worth the drive, the stocking record is the fishing report. Idlewild is a put-and-take angling fishery, stocked with catchable game fish: 83 recorded releases totalling 71,683 fish (Westslope (Yellowstone) Cutthroat Trout, Rainbow Trout, Brook Trout), last stocked 2025-05-20.

It is still stocked (most recent release 2025-05-20), so it fishes as a put-grow water: this season's fish come from the latest cohorts, topped up to keep it going. The chart below shows the release history by year and species.

Idlewild fishes as a put-grow stillwater: work chironomids under an indicator over the shoals in spring, then leech and attractor retrieves along the drop-offs as the shallows warm. The stocking record below is the truest read on the size and cohort of fish you will find.
