Fishing at Patapsco Valley State Park
You can fish almost the whole length of the Patapsco River through Patapsco Valley State Park. The best-known spots are the McKeldin Area, where fast water and pools at the confluence of the north and south branches give good spring trout fishing, and the Daniels Area, where smallmouth bass bite year-round and rainbow and brown trout are stocked each spring. All activity is banned within 300 feet of any dam. Below the Thomas Viaduct the river is tidal, and Maryland's license and rules differ above and below that line.
Fishing at a Glance
Where to Fish
McKeldin Area. The north and south branches meet here, and DNR says the fast water and shallow pools make for excellent spring trout fishing. The 0.7-mile Rapids Trail leads to a cascade and a large, deep pool that DNR calls a great spot for anglers of all ages. Swimming there is banned because of undercurrents. See McKeldin Area.
Daniels Area. Fish above and below Daniels Dam, outside the 300-foot zone. Smallmouth bass are here all year, and the stretch is a put-and-take trout area stocked with rainbow and brown trout in spring. You can cast into the swift water below the dam minutes from your car, or paddle up the two miles of flat water behind it and fish on the float back. See Daniels Area.

Hollofield Area. Reach the river by the Union Dam Trail or the River Ridge Trail, both short and fairly steep. Anglers can also use a dirt lot beside the bridge and railroad tracks where Old Frederick Road crosses the river. See Hollofield Area.
Avalon, Orange Grove and Glen Artney. The whole river here is open, except within 300 feet of the Bloede Dam site. River access is about a tenth of a mile from the Avalon and Orange Grove lots. See Avalon Area.

Snakes on the Rocks
The sunny rocks at the McKeldin Rapids draw northern water snakes and the occasional copperhead, one of Maryland's two venomous snakes. Watch where you put your hands. Native snakes are protected by state law.
