Protected by Seneca Creek State Park during its 14-mile journey between Clopper Lake and the Potomac River, Seneca Creek provides a great medium-sized creek fly fishing experience right in Montgomery County. Spring stocking of rainbow trout starts three seasons of fly fishing opportunities at this Trail site, followed by summer and fall fishing for smallmouth bass and redbreast sunfish. Parking lots set up for accessing the Seneca Creek Greenway Trail also provide convenient access to Seneca Creek where you can fish from shore or wade into the creek. At the same time, the miles of fishable creek ensures you can spend an entire day enjoying this Trail site all to yourself.
