The Gunpowder River is a year-round trout fishery with the best times to fish being from April through November.


Gunpowder State Park, Baltimore County, MD
The Gunpowder River starts its journey below Prettyboy Dam as a tailwater flowing through a deep gorge-like setting showcasing huge boulders which make the hike up the river challenging and beautiful. As the river continues farther downstream the river bed flattens out a but making hiking and wading a bit easier before the confluence with Little Falls, a tributary that adds more volume to the river as it continues towards Loch Raven Reservoir.

Typical Weather:

Spring: Mid-March thru Mid June. Begginning in March, the weather can be cold at times with some occasional precipitation. May brings warmer temps and some of these days can still have a bit of coolness in the air. As June approaches, temperatures warm. Temperatures typically range in the 50s to the upper 70s F.

Summer: Mid June thru early September. This time of the year, the early mornings and late afternoon/evenings will provide the most comfortable fishing conditions. With temperatures in the 70-90 degree range, wet wading is a popular approach to fishing during this time of year.

Fall: September thru late November. The days start to get shorter and much cooler making a full day on the river a comfortable outing. Temperatures range from the upper 70s in September to the mid to low 50s in November.

Winter: Late November thru early March. As water temperatures begin to drop, fish tend to move less and eat less, especially in January thru February. Fishing efforts will be concentrated on the warmest parts of the day. Temperatures range from the low 40s to the mid 50s.

Rated 5 out of 5 by from The Perfect Guide My wife and I went fishing with Bryan twice recently and both were fantastic experiences. He patiently helped us get started on the water and knew how to pace the day for an enjoyable outing. While we are relative novices we have worked with fishing guides in the past. Bryan is easily the best. We plan to be repeat customers.

Rated 5 out of 5 by from Fun Day on The Gunpowder River My son and I really enjoyed our day on the Gunpowder with Bryan. He was very knowledgeable where to fish and the best presentation. He was also very aware of our individual abilities and worked well with both of us to improve our skills and enjoyment of the day. I would definitely recommend Bryan to my friends.

Rated 5 out of 5 by from Unskilled becomes SKILLED!! My wife and I had NEVER been fly fishing before in our lives, having raised (3) children and for 30+ years them being our focus. Bryan was able to very skillfully integrate his previous experiences, meeting us right where we needed to be in terms of teaching style, equipment that was exceptional, surroundings and pace....if you are looking for a guide who "gets it" and puts the client first above all else. Bryan Donoway is your "Go To" guide!

Rated 5 out of 5 by from Expert guide and teacher I took my 10 year old for his first fly fishing lesson with Bryan on the Gunpowder River. Leading up to the trip Bryan provided quick and useful replies to all questions and provided good recommendations for gear as well as suitable clothing for the changeable spring weather. On the river, high quality gear was provided as well as a good lunch. Bryan was friendly, patient, and provided appropriate advice for the two of us. He was excellent with my son in terms of tone, approach, and advice as well as providing encouragement when it got a little cold or boring, but also allowing space to for him to have breaks when needed - my son loved the day and got so much out of it. With me, Bryan provided a great balance of advice and direction while providing space to permit free fishing which was a lovely balance. Bryan knew every inch of the river and helped guide us to understand the river as much as the fishing techniques. A wonderful day with an expert guide and teacher. Would highly recommend!

Rated 5 out of 5 by from Great Trip! Bryan is a fantastic guide and will definitely be recommending him to my friends and family. Bryan is extremely knowledgeable, helpful and friendly. He was able to teach us which flies to use in certain scenarios, cast, survey the river for ideal fish locations and proper fly fishing edict. With his teaching we were able to find the fish in no time!

Rated 5 out of 5 by from Another Great Trip This was my 4th trip with Bryan. As in all 4 cases Bryan is professional, engaging, and full of great feedback. I started with an instruction class 2 years ago and have been on 3 guided trips with Bryan over the past 18 months. I look at these trips as a way to improve my skills as I am new to fly fishing. It’s not always about catching fish while you’re on a trip. It’s what you take from the trip when you’re out on your own and what you learned improves your skills. Best wishes & thanks! Tony B

Rated 5 out of 5 by from Expert Instructor Bryan was great, he was very thorough with explaining techniques and the important details for a successful fly fishing trip. He took us to a very lightly fished location so we weren't competing with other fisherman. The equipment he provided was also high quality. I will definitely make fly fishing a new hobby
