- Medicine Lake NWR is situated on the glaciated plains in the northeast corner of MT. The refuge lies in the highly productive prairie pothole region. It is a prairie refuge located in the transition zone between the mixed and short grass prairie.
The refuge contains a series of impoundments, water control structures, and canals that are used to maintain optimum water conditions for waterfowl management. Management of the refuge native grasslands is aimed at providing quality nesting cover for waterfowl and other migratory birds.
The refuge has the largest white pelican rookery (9000+) in MT which produces over 2,300 young in an average year. An active breeding population of endangered piping plovers are supported on refuge lands. The refuge has a large portion of the native mixed grass prairie still intact. This habitat is home to many native grassland bird species such as Baird's and LeConte's sparrows, Sprague's pipit, ferruginous hawks and burrowing owls.
