Moon Beam is a public lake in Ada County, Idaho, managed by Idaho Department of Fish and Game. It is public water managed for fishing by Idaho Fish and Game.
Lakes and reservoirs across the Rocky Mountain region typically hold rainbow, brown, cutthroat and brook trout, with kokanee salmon and lake trout present in many of the larger reservoirs -- species commonly documented across the region's public waters by state wildlife agencies.
Moon Beam covers about 22 acres in the Southwest Idaho region. The nearest other mapped waters on PiscaMaps are Eagle Island Park Pond and Eagle Island Park Pond East.
Anyone 14 or older needs an Idaho fishing licence — the resident annual is about $30.50, the non-resident annual about $98.25 (Idaho's non-resident fee is one of the highest in the country), with a non-resident 1-day (~$23.50) plus $6/consecutive-day option. Steelhead and salmon each need a separate permit. Idaho residents 65 and older buy a reduced-fee licence; under-14 fish free with a licensed adult. Buy from IDFG at idfg.idaho.gov. An Idaho fishing licence covers this water — it is on IDFG's public-waters hydrography (steelhead and salmon each need a separate permit).
