LEVEL OF CONCERN: CRITICAL
Northern California (NC) summer steelhead are in long-term decline and this trend will continue without substantial human intervention on a broad scale. They are vulnerable to extinction by 2050 due to their reliance on cold water during the warmest months and are critically susceptible to climate change.
Sufficient flows and cool temperatures are rapidly disappearing across the Northern California (NC) summer steelhead DPS range during critical over summering months. This is largely due to drought-related flow reductions and illegal and unregulated diversions to support exploding marijuana cultivation.
