Lake Mary Ronan Professional Review and Guide
"Lake Mary Ronan is one of the few lakes in Montana not open to year-round fishing. The fishing season on this 1,500-acre lake is closed from February 28 through the third Saturday in May in order to allow undisturbed spawning for the lake’s self-sustaining rainbow trout population. This lovely lake, located in rolling timbered hills and mountains, has become a popular summertime recreation spot for anglers, boaters, water-skiers, and picnickers.
There are a number of private cottages and cabins situated around the shoreline. The cast side of the lake houses the Lake Mary Ronan State Park. This site provides public camping, boat access, toilets, and a picnic area. Lake Mary Ronan is a highly popular fishery from June through February for rainbow and cutthroat trout, kokanee salmon, and largemouth bass. With that array of fish from which to choose, the lake is an angler’s smorgasbord, although most anglers who visit the area seem to concentrate their efforts on bringing home a creel of salmon. But the lake does have its dedicated trout anglers and hardcore bass fanatics."
