PROCEEDINGS OF THE DESERT FISHES COUNCIL, 1994 SYMPOSIUM VOLUME XXVI - published 1995 naturales que reducieron dramaticamente a dos poblaciones y eliminaron a otra, a tal grado que dicha propuesta pueda ser recomendada para despuds. ENTSCH,L.D. (LDL - Utah Division of wildlife, Salt Lake City, Utah) Utah's Native Fish Program: A review of activities in 1994 Programs de Peces Nativos de Utah: Una revision de las actividades en 1994 KEYWORDS: Utah; native fishes ABSTRACT The native fish program within the Utah Division of Wildlife (UDWR) is divided into four major components: (1) native fish (not federally listed), (2) Virgin River fish, (3) June sucker, and (4) Colorado River Fish (Upper Basin and San Juan). During 1994, UDWR was restructured and these programs were added with sportfish programs into a new Aquatic Section. Despite a significant reduction in force, efforts in the native fish programs have generally been maintained. In some cases, the program has expanded. Activities within each component are summarized and highlights are presented. CLAVES: Utah; peces nativos RESUMEN El programa de peces nativos en The Utah Division of Wildlife (UDWR), esta dividida en cuatro componentes principales: (1) peces nativos (no federalmente enlistados), (2) peces del Rio Virgin, (3) June sucker (matalote de Junio), y (4) peces del Rio Colorado (Cuenca alta y San Juan). Durante 1994 la UDWR fue re-estructurada y estos programas fueron sumados en los programas de pesca deportiva en una nueva Seccion AcuAtica. A pesar de una significante reducci6n de fuerza de trabajo, los esfuerzos en los programas de peces nativos generalmente han sido mantenidos. En algunos casos el programa se ha expandido. Las actividades en cada componente se presentan en forma sumaria enfatizada. BOLSTER B-C: ?

Recent drought and agricultural diversion in the and Goose Lake Basin caused the lake to dry completely the past three years. The Basin contains the following endemic Species of Special Concern: Goose Lake lamprey (Lampetra tridentata ssp.), Goose Lake redband trout (Oncorhynchus mykiss ssp.), Goose Lake tui chub (Gila bicolor thalassina) and Goose Lake sucker (Catostomus occidentalis lacusanserinus). The Department participates in the Goose Lake Fishes Working Group. The Group provides a mechanism for conflict resolution between resource managers and landowners, and is developing a cooperative plan to hopefully preclude the need to list these species. The Department had a field crew at Goose Lake for the past two field seasons. In 1993, the crew habitat-typed one of the major tributaries, Willow Creek and its tributaries. In 1994, the various habitat types were surveyed for species composition. The lake's remnant trout population is gone, but may be recolonized by remaining stream populations. Relatively good numbers of suckers and chub were found. Lamprey were not very abundant. Some of the tributaries included exotic brown trout and fathead minnows. MODOC SUCKER - Until 1973 the Modoc sucker (Catostomus microps) was known only from its type locality, Rush Creek in Modoc County, where it was first collected in 1898. It is now known to occur in nine streams. Until surveys of six of the streams by the USFWS (Scoppettone et al.) in 1992, this federal- and state-listed endangered species was thought to be on the brink of extinction. The 1992 survey indicated that the species is relatively secure in five of the six streams surveyed. Department activities include ongoing review of timber harvest plans and flow monitoring at some sites. SHORTNOSE AND LOST RIVER SUCKERS - California populations of the shortnose sucker (Chasmistes brevirostris) and Lost River sucker (Deltistes luxatus) continue to be in peril. Major populations of these federal- and state-listed species occur in the Clear Lake Reservoir watershed in the upper Klamath River and Lost River systems of extreme northeastern California. Recent drought conditions have reduced the habitat available and long-term effects are unknown. In October 1992, Clear Lake reservoir reached the lowest elevation since 1935 and 15
