April in Maine marks the unofficial start of fly fishing season, and while the weather can still be unpredictable, it’s one of the most exciting times to be on the water. At Maine Fly Company, we know firsthand that early spring can produce some of the most memorable days on the river—if you come prepared with the right mindset and the right gear.
Water temperatures in April are still cold, typically ranging from the high 30s to mid-40s, so trout and salmon aren’t chasing fast-moving flies just yet. This is the time to slow things down and focus on presentation. Nymphs are hands-down the most productive flies in April. Patterns like the Pheasant Tail, Hare’s Ear, and Copper John are classics for a reason—they mimic the aquatic insects that are active under the surface and are irresistible to trout this time of year. Dead-drifting a double nymph rig with some added split shot can help get your flies down to the strike zone, where fish are holding close to the bottom in slower-moving water.
Streamer fishing can also be highly effective, especially on cloudy days or during high-water periods after snowmelt. Woolly Buggers in olive, black, or white are solid go-tos, as are smaller baitfish patterns like the Muddler Minnow. The key is to vary your retrieve—sometimes a slow, steady strip works, and other times a more erratic movement will trigger a strike. If you’re targeting landlocked salmon in rivers like the Kennebec or the Rapid, streamers can produce explosive takes.
While dry fly action is limited in early April, don’t write it off completely. If we get a warm stretch, you might catch a small window of surface activity, especially with early black stoneflies or midges. Keep a few small dries in your box just in case—you never know when opportunity will rise.
Waders and layers are essential. April in Maine can throw everything from snow flurries to 60-degree sunshine your way, often in the same afternoon. And don’t forget to bring a good net and barbless hooks—we’re all about protecting these wild fish and the waters they call home.
At Maine Fly Company, we’re proud to build rods that are as ready for April conditions as you are. Cold water, early season hatches, and that first bend in the rod after a long winter—there’s nothing quite like it.
