It’s easy to be confused by the name Long Lake. Maine has more than25 lakes so-named—and nearly as many bodies of water with the name Long Pond. At the northern tip of Maine is Long Lake in St. Agatha, where many towns are identified by letters and numbers—representing township and range—rather than by name. Long Lake sits mostly within St. Agatha, T17, R3 and T17, R4.
This lake is the deepest of the Fish River chain of lakes and covers 6,000 acres with a maximum water depth of 163 feet. The surrounding land is primarily agricultural and forestland and has a number of camps and cottages along the shorelines. Brook trout and landlocked salmon in Long Lake average about 16 inches in length and weigh an average of 5 pounds. You can go ice fishing here from Jan. 1 through March 31.
You can access the lake in St. Agatha on the western shore alongside Route 162 or at the southwestern tip in Sinclair. You can also use a remote small boat access at the end of Lake Road on the extreme southern tip of Long Lake. Floatplane access is also available alongside Route 162 just north of Sinclair. You can find lodging, guides and other services in St. Agatha or the nearby border town of Madawaska.
