A prolonged drought in North Central Montana is affecting Freezeout Lake water levels. This in turn is affecting bird migration patterns. Birds stop at Freezeout Lake for food and rest before continuing their migration to Canada and Alaska. Swans, geese, and other migratory birds use Freezeout Lake as a seasonal stop. Less water means other environmental challenges including lost fish habitat and build-up of sediment. Bird watchers world-wide visit Freezeout Lake to watch shorebirds, raptors, prairie birds, and waterfowl. With fewer birds, tourism is also affected by the lower water levels.
