“The Maryland Department of Natural Resources (DNR) will release more than 24,000 Brown, Rainbow and Golden Trout into Maryland’s freshwater streams and ponds this month.
“Stocking dates and locations are dependent on water flow and water temperatures,” said DNR Inland Fisheries Director Don Cosden. “Based on current conditions, we anticipate stocking to commence in many places beginning the second week of October.”
DNR fisheries biologists will release approximately 23,000 Rainbow and Golden Trout in the one-pound size range, and about 1,000 similarly-sized Brown Trout. They will also stock about 150 Rainbow and Golden Trout in the two- to three-pound range.
Fall stocking locations include popular fishing areas such as the North Branch Potomac, Bear Creek, Town Creek, Blairs Valley Lake, Morgan Run, Patapsco River, Gunpowder Falls, Great Seneca, Wheatly Lake, Lake Artimesia, Greenbelt Lake, Big Elk, Deer Creek and Tuckahoe. Some stocked streams have seasonal restrictions on keeping trout”.
