Few, if any, Lahontan cutthroat trout remained in Mann Lake as drought and low mountain snowpack caused the level of the lake to drop by as much as half. The Oregon Department of Fish and Wildlife was not sure it would be able to restock cutthroats again this spring as low as the water was. The meager amount of water meant that there was not enough total dissolved oxygen for the fish. There has not been enough precipitation to fill Mann Lake in the last five to eight years, according to Dave Banks, district fish biologist for ODFW. The lake was six to seven feet deep in 2015 and was down to three to four feet in depth in early 2018. Klamath Falls Herald and News (Ore.), April 3, 2018
