    CHAPTER 6 Fisheries and Aquatic Resources CHAPTER 6 FISHERIES AND AQUATIC RESOURCES This chapter describes the existing fisheries and aquatic resources conditions, the applicable regulations, and potential impacts from implementation of the Proposed Project Alternative and other alternatives on the fisheries and aquatic resources in the Project Area. 6.1 ENVIRONMENTAL SETTING This section describes the environmental setting related to fisheries and aquatic resources that may be influenced by implementation of the Proposed Project Alternative or other alternatives in the Project Area including Lake Mary, Mammoth Creek extending from Lake Mary to its confluence with Hot Creek, and Hot Creek from its confluence with Mammoth Creek downstream to the USGS Hot Creek Flume Gage. 6.1.1 LAKE MARY Lake Mary is a cirque lake (a deep, steep-walled basin on a mountain) formed by the filling of remnant moraine depressions left by receding glaciers (USGS 1999). Lake Mary contains prominent granite features, and cold, clear water, making it a popular angling destination. A "fishing enhancement" program is implemented by both the Town of Mammoth Lakes and CDFG to maintain the lake’s appeal as a “trophy” trout destination. The recreational fishery in Lake Mary is maintained by both the Town of Mammoth Lakes and CDFG because of its economic importance to the Mammoth Lakes Basin (Mammoth City Concierge 2010). Lake Mary has been, and continues to be managed as a put-and-take recreational fishery. Hatchery rainbow trout have been regularly planted by CDFG beginning in the late spring and extending through the summer. The lake also is often planted with “Alpers trout.” The Alpers trout is a genetic hybrid of rainbow trout, Kamloops trout and steelhead, raised in the streams and ponds of Alpers Owens River Ranch.

  • A Preliminary Survey of the Aquatic and Semiaquatic Hemiptera
    Polhemus and Polhemus: Aquatic Hemiptera of Desert Hot Springs 1 A preliminary survey of the aquatic and semiaquatic Hemiptera occurring in the springs of the Railroad Valley, White River, and Amargosa River drainage systems, Nevada and California, with special reference to thermal relicts Dan A. Polhemus Dept. of Entomology, Bishop Museum, P. 0. Box 19000-A, Honolulu, HI 96817 ard John T. Polhemus Univ. of Colorado Museum, 3115 S. York St., Englewood, CO 80110 INTRODUCTION One of the most remarkable concentrations of disjunct and endemic aquatic Hemiptera in North America is found in the thermal refugia of the Railroad Valley, White River, and Amargosa River drainages of Nevada and California. These drainages represent former tributaries to the Colorado system that were continuous systems in the Pliocene and Pleistocene, but have been subsequently dessicated and reduced to discontinous spring fed aquatic refugia. The thermal springs of these three systems contain a large number of endemic aquatic Hemiptera species, as well as many highly disjunct populations of other taxa. The current report details the distributions of these species, addresses certain taxonomic problems relating to them, and considers the biogeographic significance of this thermally relictual fauna. LOCALITIES SAMPLED The information upon which this report is based has been collected by the authors over a period of thirty years, and in many cases the passage of several decades has seen a serious degredation of the aquatic habita~s listed below. For this reason an attempt has been made in the last three years to revisit many of the most critical habitats and &scertain the status of their aquatic Hemiptera faunas.

  • Climate Impacts on Streamflow Dynamics of Mammoth Creek and the Upper Owens River, California
    University of Nevada, Reno Climate Impacts on Streamflow Dynamics of Mammoth Creek and the Upper Owens River, California A thesis submitted in partial fulfillment of the requirements for the degree of Master of Science in Hydrology by Susan Burak Dr. Justin Huntington, Thesis Advisor August, 2015 THE GRADUATE SCHOOL We recommend that the thesis prepared under our supervision by SUSAN BURAK Entitled Climate Impacts On Streamflow Dynamics Of Mammoth Creek And The Upper Owens River, California be accepted in partial fulfillment of the requirements for the degree of MASTER OF SCIENCE Justin Huntington, Ph. D., Advisor Scott Tyler, Ph. D., Committee Member John Naliboff, Ph. D., Committee Member Jim Thomas, Ph.D., Graduate School Representative David W. Zeh, Ph. D., Dean, Graduate School August, 2015 i Abstract Mammoth Creek and the Upper Owens River, located in the eastern Sierra Nevada, are the primary headwater supply for Mono County and the City of Los Angeles. Population and economic growth continue to increase pressures on water supplies in the Town of Mammoth Lakes and Los Angeles, therefore a more thorough understanding on the physical processes and empirical relationships between climate and streamflow in these headwaters is warranted. Climate in the study area is characterized by large-scale features of general circulation and orography, resulting in high spatial and temporal variability. Snowmelt provides for groundwater recharge and streamflow throughout the spring, early summer, and late season low flow periods. This thesis examines how lags between climate and streamflow are related to headwater catchment geology and hydrogeology. Empirical relationships between climate and streamflow are evaluated for Mammoth Creek and the Upper Owens River with the Standardized Precipitation Evapotranspiration Index (SPEI) at 12, 15, 24, 36, and 48-month timescales, and standardized streamflows.

  • Bruneau Hot Springsnail 2004 Range Wide Survey May 17, 2005
    Bruneau Hot Springsnail 2004 Range Wide Survey May 17, 2005 Prepared by Cary Myler U. S. Fish and Wildlife Service Boise, Idaho INTRODUCTION The purpose of this study was to locate and measure physical characteristics of thermal spring habitats containing Bruneau Hot Springsnails (Pyrgulopsis bruneauensis) in the Bruneau Hot Springsnail recovery area. This report presents information gathered 17– 19 November 2004 and February 3, 2005 regarding the present distribution and relative abundance of Bruneau Hot Springsnails (Pyrgulopsis bruneauensis) in thermal springs, seeps, and thermal upwellings along a 6.5–km reach of Bruneau River, Idaho. Additionally, information is presented regarding specific conductance and temperature of the springs. P. bruneauensis is a spring dwelling snail endemic to thermal springs along Bruneau River southeast of Mountain Home (Mladenka and Minshall 2001). The present study and previous surveys conducted in 1991, 1993, 1996, and 2003 documented P. bruneauensis presence and spring conditions upstream and downstream of Bruneau River confluence with Hot Creek; however, surveys completed in 1998, 2000, and 2002 only addressed sites upstream of Hot Creek. METHODS Study Area P. bruneauensis were surveyed along approximately 6.5-km of the Bruneau River (USGS 7.5 minute quadrangles: Hot Spring, Crowbar Gulch). This reach comprises the designated Recovery Area as described in the Recovery Plan for the Bruneau Hot Springsnail (USFWS 2002). The Recovery Area is defined as the intersection of Bruneau River with the southern boundary of Township 08 South, Range 06 East, Section 12 and continues downstream (including Hot Creek from its confluence with Bruneau River to Indian Bathtub) to the intersection of Bruneau River with the northern boundary of Township 07 South, Range 06 East, Section 35 of Owyhee County, Idaho (Figure 1).

    U.S. GEOLOGICAL SURVEY and the U.S. FOREST SERVICE—OUR VOLCANIC PUBLIC LANDS Boiling Water at Hot Creek—The Dangerous and Dynamic Thermal Springs in California’s Long Valley Caldera he beautiful blue pools and Timpressive boiling fountains along Hot Creek in east-central California have provided enjoyment to generations of visitors, but they have also been the cause of injury or death to some who disregarded warnings and fences. The springs and geysers in the stream bed and along its banks change location, temperature, and flow rates frequently and unpredictably. The hot springs and geysers of Hot Creek are visible signs of dynamic geologic processes in this volcanic region, where underground heat drives thermal spring activity. Hot Creek flows through the Long Valley Caldera in a volcanically active region of east-central California. This stretch of the creek, looking upstream to the southwest, has long been a popular recreation area because of the warm waters from its thermal springs. These springs, however, are In the Hot Creek Geologic Site, located unpredictable and can suddenly erupt with violence and at boiling temperature. Because of this danger, the U.S. Forest Service has had to close parts of the Hot Creek Geologic Site to visitors. in a narrow gorge 8 miles (12 km) east of (USGS photo by Chris Farrar.) the town of Mammoth Lakes, numerous hot springs flow into a snowmelt-fed stream.
