The Lahontan cutthroat trout is native to the Lahontan basin of northern Nevada, Eastern Sierra of California, and southern Oregon. The primary hope for Lahontan cutthroat lies with the increasingly rare perennial streams that flow cold and clear through the dry sagebrush country of the Great Basin. Following decades of decline, the species was listed under the Endangered Species Act in 1973. However, fire suppression, coupled with climate change, has made modern fires more frequent, severe and catastrophic. They grow about one inch per month once stocked. Each September, California Department of Fish and Wildlife heads to the lake with electrofishing boats to remove adult brook trout and other nonnative fishes from the lake while Trout Unlimited crews, funded by the National Fish and Wildlife Foundation, work on the creek. The transition from relatively frequent understory fires to less frequent, but catastrophic, crown fires can have a severe impact on fish habitat and wipe out populations with narrow habitat ranges. According to Gerstung, a swath of California waters from Lake Tahoe south to Lake Crowley are being managed under DFG's Heritage Trout program and the U.S. The largest recorded Lahontan trout weighed in at 41 pounds.

The Lahontan Cutthroat Trout (Oncorhynchus clarki henshawi) is native to the Lahontan basin of northern Nevada, northeastern California, and southeastern Oregon. We can work together to ensure that California will always have resilient populations of wild fish thriving in clean, cold water streams. The Lahontan cutthroat trout is one subspecies of the wide-ranging cutthroat trout species (O. clarki) that includes at least 14 recognized forms in the western United States. Resulting impacts include water diversions, groundwater pumping, streambed alteration (to protect houses from flooding, construct road crossings, etc. Lahontan Cutthroat Trout Lahontan cutthroat are native to streams and lakes of the Lahontan basin in California, Nevada, and Oregon. Lahontan cutthroat—the state fish of Nevada—are a large, bright-orange species of cutthroat that once were abundant across thousands of miles of streams in the Great Basin.

Mercury mining, used for processing gold in placer and dredge mining, left a lasting negative impact on wildlife. ), and pollution (especially from septic tanks and illegal waste dumping). These fish average 8 to 9 in (20 to 23 cm) in small streams and 8 to 22 in (20 to 56 cm) in larger rivers and lakes. Prior to joining CalTrout, he worked with the Fisheries Leadership & Sustainability Forum, a non-profit that supports the eight federal regional fishery management councils around the country. In order to protect the integrity of fishable populations, special fishing restrictions are in place in some waters. To help combat the continued declines, populations have been established in nine creeks outside of their native range in California through stocking from source populations and protected by man-made and natural barriers. Lahontan Cutthroat trout are closely related to the Paiute Cutthroat trout found in the Carson River Basin. They are native to the Lahontan basin of northern Nevada, northeastern California, and southeastern Oregon. Trout spawning: Lahontan cutthroat trout spawn in Upper Independence Creek, from end of May to mid-June.

Since 2002, 76,547 Lahontan cutthroat trout have been reintroduced into Fallen Leaf Lake, California; we used creel surveys, diet data, mark–recapture methods, bioenergetics modeling, and netting data across seasons to evaluate the habitat use, growth, and relative abundance of Lahontan cutthroat trout and the abundance, diet, habitat use, and predation by nonnative species. Improperly managed logging increases sediment in streams, increases solar input which increases stream temperatures, and degrades riparian cover. Photo Credit: Gregg Ritland for the U.S. The Lahontan Cutthroat Trout Long ago, the now rare Lahontan Cutthroat Trout migrated its way up the Columbia River system and established residence in Lake Lahontan, the giant prehistoric inland sea that covered areas of Northern California and Nevada. Many heavily logged watersheds once supported the highest species diversity and abundance of fishes, including anadromous salmon and steelhead. These fish hybridize with native redband, rainbow, Golden, and Cutthroat trout, and their offspring replace genetically pure populations in the limited habitats they still occupy. Fishing season runs from October 1st to June 30th, with the peak season being December-April. Such mining is now largely banned, but lasting impacts remain in many areas. Dr. Lusardi resides at the UC Davis Center for Watershed Sciences and works closely with Dr. Peter Moyle on numerous projects to help inform California Trout conservation policy.
