Kern river rainbows have been successfully introduced into the Kaweah-Kern river and Chagoopa creek. Historically, Kern River Rainbow trout could be found throughout the Kern River and its tributaries in Tulare County. Ensuring resilient wild fish thrive in healthy waters for a better California. Mike Stevens. [5] Its current range is drastically reduced from its historic range. Populations of many rainbow trout subspecies, including anadromous forms (steelhead) of O. m. irideus (coastal rainbow trout) and O. m. gairdneri (Columbia River redband trout) have declined in their native ranges due to over-harvest, habitat loss, disease, invasive species, pollution and hybridization with other subspecies, and some introduced populations, once healthy, have declined for the same reasons. The golden trout is normally found in the Golden Trout Creek, Volcano Creek, and the South Fork Kern River. Based on CDFW surveys in 2009 and expert judgment, they currently persist in about 20 km (12 mi.) Today populations considered Kern River rainbow trout live in the Kern River from Durrwood Creek upstream to Junction Meadow. The majority of remaining unhybridized Kern River Rainbows are upstream of natural and/or man-made barriers and isolated from other populations, and their status could deteriorate rapidly due to a lack of population connectivity. Patrick Samuel is the Conservation Program Coordinator for California Trout, a position he has held for almost two years, where he coordinates special research projects for California Trout, including the State of the Salmonids report. Harvest relates to legally regulated commercial, tribal, and recreational fisheries, as well as illegal harvest (poaching). Inland trout can also be impacted with stocking of hatchery fish for recreation. The fly fishing on the upper Kern River is legendary and Kern River Fly Fishing offers guided pack trips into the Golden Trout Wilderness by horseback and pack animals to fly fish for native Kern River Rainbow Trout, Little Kern Golden Trout and our state fish, "The Golden Trout" in some of the most beautiful places found on earth. }} } );jQuery(document).bind('gform_post_conditional_logic', function(event, formId, fields, isInit){} ); jQuery(document).ready(function(){jQuery(document).trigger('gform_post_render', [37, 1]) } ); California Trout is a 501(c)3 nonprofit organization, tax ID #23-7097680.

Adult size: in streams up to 19-20 cm SL, in lakes up to 35-43 cm FL, max 71 cm TL (5.0 kg) Non-native species (including fishes and other aquatic organisms) are ubiquitous across many of Californiaâs watersheds; their impacts on native species through hybridization, predation, competition, increased disease transmission, and habitat alteration can be severe. The Golden Trout are thought to be derived from the rainbows that were isolated about 70,000 years ago by both glacial and tectonic activity. As a consequence, some rainbow populations, particularly anadromous forms within their native range, hav… Downstream, dams alter the timing, frequency, duration, magnitude, and rate of change of flows decreasing habitat quality and survival. ), and pollution (especially from septic tanks and illegal waste dumping). -. 391. The rainbow trout found below Lake Isabella are different as they have bread for years with coastal and hatchery trout. Kern River Rainbow trout are a distinct subspecies of Rainbow trout that likely resulted from natural hybridization of Coastal Rainbow trout with Little Kern Golden trout several thousand years ago. The Kern River rainbow trout (Oncorhynchus mykiss gilberti) is a localized subspecies of the rainbow trout (Oncorhynchus mykiss), a variety of fish in the family Salmonidae. Dams block access to historical spawning and rearing habitats. CDFW photos by Jeff Weaver. Most estuaries in the state are highly altered from human activities, especially diking, draining, and sandbar removal between the estuary and ocean. This factor refers to hard rock mining, from which contaminated tailings, mine effluents, and toxic pollutants may have been dumped or leached into streams, mostly from abandoned mines. It is found in a short section of the main stem of the Kern River and several tributaries in the southern Sierra Nevada mountains in California. Using the best estimates of approximately 200-1,500 trout per km (1.2 mi. [3], The Kern River rainbow trout is one of three subspecies of O. mykiss that are all endemic to the Kern River basin, sharing the headwaters of the river with the Little Kern golden trout and golden trout. Impacts from agriculture include streams polluted by agricultural return water or farm effluent; reduced flow due to diversions which can affect migratory patterns; and increased silt and pesticides in streams. Kern River Rainbow Trout. Its historic range in the main stem of the Kern River it probably extended downstream below where Isabella Dam is today and upstream in the South Fork of the Kern River as far as Onyx creek. He is author or co-author of more than 240 publications, including the definitive Inland Fishes of California (2002). Big Kern Lake (it’s actually a river for the length of the season, but sometimes creates a lake in high water years) is one of the premier fishing locations in the Golden Trout Wilderness. Regularly sample populations to determine distribution, abundance, and genetic structure, and to identify any changes in the speciesâ status. Email* Erickson (2103) performed a detailed genetic analysis of upper Kern Basin trout in the historic range of Kern River rainbow trout, using single Copy link. Shopping. As Californiaâs population grows, rural development increasingly encroaches along or near streams. awesome fishing on the kern river!!! Improperly managed logging increases sediment in streams, increases solar input which increases stream temperatures, and degrades riparian cover. Review, revise, and implement grazing management to restore ecological function of watersheds. Placeholders.enable(); Kern River rainbow trout were once widely distributed to the upper Kern River basin, Tulare, and Kern Counties. New facilities recently constructed at the Kern River Hatchery in Kernville are designed… Privacy PolicyââContact UsââNewsââDonate. Kern River Rainbow are fairly nonspecific on flies and plentiful. Despite its limited distribution, there are two recognized subspecies of golden trout. KERN PERFECTION – Fly angler Randal Garrett with a 21-plus inch wild rainbow caught while nymphing the upper Kern River near Johnsondale Bridge. His recent research interests include Coho salmon on the Shasta River, the ecology of volcanic spring-fed rivers, inland trout conservation and management, and policy implications of trap and haul programs for anadromous fishes in California. It is the state freshwater fish of California. Search For the Kern River Rainbow: A Walk Through the High Sierra Follow Craig through a 24-day unassisted wilderness jaunt through the Golden Trout Wilderness in this short video. he Kern river rainbow trout is one of three trout endemic to the Kern basin; the others are the little Kern and California golden trout. ), total numbers of Kern River Rainbow trout are likely between 4,000 and 30,000 fish, though are likely at the lower end of this range due to habitat degradation and hybridization. Sierra Way follows the Kern River for 22 miles to the Johnsondale Bridge. and 3.6 kg (8 lbs. The idea then was for state workers and volunteers to hike to a remote creek in the southern Sierra Nevada to find genetically pure Kern River rainbow trout.
