Flagstaff Lake, a magnificent waterbody nestled in Somerset County, Maine, spans an impressive 20,300 acres, offering an expansive and captivating landscape for both anglers and nature enthusiasts. Located to the north of the majestic Bigelow Mountain range, this lake came into existence in 1950 through the construction of a dam on the Dead River. Flagstaff Lake is renowned for its remarkable fishery and stunning natural surroundings. This vast lake is primarily fed by two major inlets, the North and South Branches of the Dead River, which gracefully merge into its western side. The Dead River then continues its journey northward, exiting the lake at Long Falls, situated in the northeast corner of this expansive impoundment. One of the defining characteristics of Flagstaff Lake is its largely undeveloped shoreline, preserving its pristine and unspoiled beauty. While Flagstaff Lake offers an abundance of natural beauty and recreational opportunities, its water quality is considered marginal for supporting coldwater gamefish. This relatively shallow lake experiences water temperatures that can reach critically high levels, posing challenges for sustaining coldwater species. However, the lake compensates with a wealth of excellent spawning and nursery habitats scattered throughout its numerous tributaries. Despite the less-than-ideal conditions for coldwater gamefish, Flagstaff Lake still provides limited opportunities for brook trout and salmon fishing. These fisheries persist, albeit with slow growth rates, due to stiff competition for resources and space from warmwater fish species. To bolster these fisheries, the lake occasionally receives salmon stocking efforts, ensuring that anglers can continue to enjoy the thrill of catching these prized species. Flagstaff Lake's accessibility is a boon to outdoor enthusiasts, with numerous boat launch sites available on both the east and west ends of the lake. Whether you're a summer angler or a winter ice-fishing enthusiast, Flagstaff Lake welcomes you under general fishing regulations. Despite its water quality challenges, the lake's natural beauty and diverse fishery make it a cherished destination for those seeking an outdoor adventure in the heart of Maine's wilderness. As this exceptional lake continues to enchant visitors with its unparalleled beauty and unique fishing experiences, responsible stewardship and ongoing monitoring are essential to preserve its delicate ecosystem and ensure that future generations can continue to cherish Flagstaff Lake's natural wonders.
