Klamath Mountains Province Summer Steelhead

Oncorhynchus mykiss irideus

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.
