LEVEL OF CONCERN: CRITICAL
Klamath Mountain Province (KMP) summer steelhead are in a state of long-term decline in the Klamath Basin. These stream-maturing fish face a high likelihood of extinction in California in the next 50 years due to their reliance on cold water sources during the warmest summer months, which are becoming increasingly rare.
Only two or three Klamath Mountain Province summer steelhead populations are large enough to sustain this unique life history throughout the next 50 years under present conditions. Most of
the smaller populations are likely to disappear due to reduced streamflows, shrinking availability of suitable habitat, and higher temperatures throughout the summer months in headwater tributaries.
