In response to litigation from the Center for Biological Diversity and Idaho Conservation League, the U.S. Army Corps of Engineers plans to revoke its permit for a marina and lakeside housing development at the mouth of Trestle Creek on Lake Pend Oreille due to impacts on bull trout listed under the Endangered Species Act. The creek accounts for more than half of the annual bull trout spawning sites in the Pend Oreille Basin.
