Deep Creek in San Bernardino County represents one of California's most significant wild trout fisheries in the southern part of the state. Located in the San Bernardino National Forest, this designated "Wild Trout Stream" flows for approximately 22 miles from its headwaters at around 6,200 feet elevation down through rugged mountain terrain before meeting the East Fork Mojave River. The creek drops about 3,000 feet over its course, creating a diverse aquatic habitat with deep pools, cascading waterfalls, and boulder-strewn sections that provide excellent trout habitat. What makes Deep Creek particularly special is its status as an unmanaged wild fishery - the trout populations are entirely self-sustaining without hatchery supplementation, making it a rare gem in Southern California's heavily developed landscape.
