On Saturday morning more than 100 anglers showed up at Bon Air Park, not far from the high-rises of Ballston, for the beginning of Arlington County’s trout season. From 9:00 a.m. to noon, the kids 15 and under has free reign of the prime fishing spots along Four Mile Run, without adult competition.
Arlington’s trout season lasts about six weeks, effectively ending when all the trout have been caught. Trout cannot naturally survive in Four Mile Run due to the lack of cool, shady spots during the summer, so the county parks and recreation department contracts with a fish hatchery in West Virginia to stock the stream from Barcroft Park to Bon Air Park every third weekend in March. An annual Four Mile Run stream clean-up, every second weekend in March, is timed to coincide with the beginning of trout fishing season.
