The Gunpowder River is the ideal destination for trout fishing in late Summer. The prolonged high air temps and lack of rain have basically shut down trout fishing on freestone streams in Maryland, Pennsylvania and New Jersey. Low flows are not the big problem, but the warmer water temps over 70 degrees can be too stressful on trout. Fortunately the frigid bottom release from Prettyboy Dam offers refuge from the hot air temps, and allows us to fish the Gunpowder without concern. Yesterday I was curious just how much river was fishable based on water temperature. The Falls Rd area is 48 degrees, and roughly six miles down river warms to 57 at Blue Mount Rd. I took a temp of 61 degrees at 1 pm by the Monkton Rd Bridge. Anglers may not encounter high water temps until they reach the Glencoe Rd section, which means there are more than eleven miles of river below 65 degrees. Last Thursday when heavy rains moved through the region, the river rose but quickly cleared above Masemore Rd. The sections down river were stained from the tributaries running high and off color, but remained fishable. The river had 8-10 inches of visibility with a lot of leaves, sticks and other debris in the water. I hoped the trout would be in feeding mode and rigged two nymphs on 5X under a Thingamabobber. The next few hours it was steady action, browns from six to twelve inches, before a late afternoon storm chased me off the water. On Friday afternoon I took my girlfriend out to catch some browns gorging themselves in the murky water, but the river was clear. She caught a few browns and missed some strikes in an hour of fishing. More storms passed through over the weekend, so I spent Monday searching for cloudy sections of the river. In an hour of nymphing I landed six browns before switching to a streamer. The brown above measured fifteen inches and my next brown was just shy of fourteen inches. In the latest video post I filmed a few browns I caught yesterday on the Gunpowder.
