The redband trout is a unique subspecies adapted to the
Malheur Lake basin ecosystem. In these closed, high-desert basins, redband trout have evolved to survive in environments with vast extremes of both water flow and temperature. They are one of only eight desert-basin populations of interior

While not an officially designated threatened or endangered species, the redband trout is recognized as important resource, and the Steens
Mountain Cooperative Management and Protection Act of 2000 (Public Law 106-399) sets aside land in Oregon for protection and research of redband trout.

Malheur Lake and has caused extreme habitat damage. Harney Lake has been inhospitable to redband trout for many years due to high alkalinities. Today, redband trout in the Malheur Lake basin are widely distributed in small- and medium-size streams.

Malheur Lake consists of ponds separated by small islands and peninsulas. The lake's central and eastern sections are more open. The generally shallow water is suitable habitat for migratory birds, waterfowl, and aquatic plants.

Malheur Lake redband comprises 10 population groups in the closed interior basin of Harney and Malheur lakes. Historically, all streams were interconnected, and these fish moved through all the lakes and streams.
