Also included are tables, graphs and data associated with this use. The data presented are valid for the period of this report, and may vary from previously published figures as water rights within the basin are subject to administrative action, such as certification, cancellation, forfeiture, or withdrawal on a continual basis. For calendar year 2019, the committed groundwater resource totaled 16,907 acre-feet, with estimated pumpage of approximately 2,303 acre-feet. This figure includes an estimated 2 acre- feet pumped from exempt domestic wells. Municipal is the largest manner of use in the basin. For calendar year 2019, pumpage for municipal use totaled 1,823 acre-feet, with appropriations of 13,600 acre-feet. The second largest manner of use was commercial with total pumpage of 478 acre-feet, and appropriations of 343 acre-feet. In January 2014, State Engineer’s Rulings 6254 through 6260 found that Coyote Spring Valley (Hydrographic Basin 13-210), Garnet Valley (13-216), Hidden Valley (13-217), California Wash (13-218), Muddy River Springs Area (13-219), and the northwestern portion of Black Mountains Area (13-215) share a unique and close hydrologic connection and in the future should be jointly managed. Consistent with the joint management of these hydrographic basins, the State Engineer has allowed changes in points of diversion between them, a practice not allowed in separately- managed basins. However, this pumpage inventory only includes details on groundwater pumping from the Coyote Spring Valley Hydrographic Basin. In January 2019, State Engineer’s Interim Order 1303 designated the administration of all water rights within Coyote Spring Valley (Hydrographic Basin 13-210), Garnet Valley (13-216), Hidden Valley (13-217), California Wash (13-218), Muddy River Springs Area (13-219), and the northwestern portion of Black Mountains Area (13-215) as a joint administrative unit known as the Lower White River Flow System (LWRFS). Additionally, State Engineer’s Interim Order 1303 held in abeyance permanent applications to change existing groundwater rights and established a temporary moratorium regarding any final subdivision or other submission concerning development and construction submitted to the State Engineer for review. 1 HYDROGRAPHIC BASIN SUMMARY HYDROGRAPHIC BASIN NUMBER 210, REGION 13 HYDROGRAPHIC BASIN NAME COYOTE SPRING VALLEY COUNTIES CLARK, LINCOLN MAJOR COMMUNITIES COYOTE SPRINGS DESIGNATED YES DENIALS BASED UPON WATER AVAILABILITY IRRIGATION GROUNDWATER LEVEL MEASUREMENTS NDWR, SNWA, USGS PUMPAGE INVENTORY, ACRE-FEET IN 2019 2,3031 STATE ENGINEER’S ORDERS NO. 905 – DESIGNATION DATE: AUGUST 21, 1985 NO. 1169 – FURTHER STUDY DATE: MARCH 8, 2002 NO. 1169A – FURTHER STUDY DATE: DECEMBER 21, 2012 NO. 1303 (INTERIM) – DESIGNATION & TEMPORARY MORATORIUM DATE: JANUARY 11, 2019 COMMITTED GROUNDWATER RESOURCE2: 16,907 ACRE-FEET DATE: JANUARY 2020 COMMERICAL……….343 DOMESTIC……….4 INDUSTRIAL……….2,500 MUNICIPAL……….13,600 WILDLIFE……….460 1 Includes pumpage by exempt domestic wells, as defined by NRS 534.013. 2 Committed groundwater resource data are accurate for January 2020. Manner of use category totals vary over time, as rights are not necessarily static. Rights may be subject to change applications, certification, withdrawals, forfeiture and cancellations; each of these circumstances could affect the duty, diversion rate and acreage associated with a given right. The value associated with each manner of use category does not include those portions that have been relinquished in support of domestic wells. A query of the NDWR Well Log Database indicates that 2 domestic wells existed in the basin during calendar year 2019. This query is assumed to represent both appropriations and exempt domestic wells. The committed domestic water resource is considered to be 2 acre-feet per domestic well, or 4 acre-feet annually. 2 PURPOSE AND SCOPE The purpose of this report is to inventory all of the groundwater resources allocated and described by the Office of the State Engineer, Nevada Division of Water Resources (NDWR), and to estimate the amount of groundwater pumped within Coyote Spring Valley for calendar year 2019. This report estimates the amount of groundwater pumped under the permits and certificates issued by the State Engineer, claims of vested right, as well as the amount pumped by exempt domestic wells within the basin. DESCRIPTION OF THE STUDY AREA Coyote Spring Valley is a basin located in southeastern Nevada, approximately 60 miles north of Las Vegas. The basin is located in Clark and Lincoln Counties (Figure 1), and is within the Colorado River Hydrographic Region. Coyote Spring Valley is bounded on the west by the Sheep Range. The south end of Coyote Spring Valley is topographically closed by a bedrock and alluvial divide extending eastward from Hayford Peak to the Arrow Canyon Range. The Arrow Canyon Range and Meadow Valley Mountains border the basin to the east. The north boundary is defined by a series of hills at the south end of the Pahranagat and Hiko Ranges and the Delamar Mountains. The adjacent Nevada hydrographic basins are Pahranagat Valley (13-209) and Delamar Valley (10-182) to the north; Kane Springs Valley (13-206) to the northeast; Lower Meadow Valley Wash (13-205) and Muddy River Springs Area (13-219) to the east; California Wash (13-218) to the southeast; Hidden Valley (13-217) to the south; Las Vegas Valley (13-212), Three Lakes Valley (Southern Part, 13-211), and Three Lakes Valley (Northern Part, 10-168) to the southwest; and Tikapoo Valley (South Subarea, 10-169B) to the west. The exterior boundary of the Coyote Spring Valley Hydrographic Basin is as described by Designation Order 905, issued by the Nevada State Engineer on August 21, 1985. GROUNDWATER LEVELS Depths to groundwater in Coyote Spring Valley are measured by NDWR and other entities. Data for actively monitored well sites (Figure 2) can be found on NDWR’s website at http://water.nv.gov/WaterLevelData.aspx, or via the Nevada Hydrology Data Mapping Application, accessible at http://water.nv.gov/mapping.aspx. Groundwater level data collected by the U.S. Geological Survey (USGS) may be accessed through their website at https://waterdata.usgs.gov/nv/nwis/gw. 3 METHODS TO ESTIMATE PUMPAGE One of the purposes of this report is to estimate the amount of groundwater pumped under vested claims, permits and certificates issued by the State Engineer, as well as the amount pumped by the exempt domestic wells in the valley. Table 1 and Figure 3 show historical pumpage by manner of use; Figure 4 shows the percentage of water pumped by manner of use; and Figure 5 compares groundwater commitments and estimated pumpage by manner of use. The following methods were used to arrive at the estimated use: • Where totalizing meters were in place, meter readings were taken and compared with previous

  • Conservation Management Strategy Coyote Springs Desert Wildlife Management Area
    Conservation Management Strategy Coyote Springs Desert Wildlife Management Area Clark County, Nevada February 2007 EXECUTIVE SUMMARY The Mojave Desert population of desert tortoises has been declining since the 1970s and was declared threatened under the Federal Endangered Species Act (ESA) in 1990. Impacts of urban growth, agriculture, recreation, and other human activities—coupled with the rise of predators and disease—are thought to be the major causes of tortoise decline. Over the past 16 years, several attempts to define and implement specific Conservation Actions (CAs), strategies, and plans have been proposed to protect the tortoise and other species considered imperiled. Clark County and the U.S. Fish and Wildlife Service (USFWS) entered into the Multiple Species Habitat Conservation Plan (MSHCP) as a binding commitment to protect 78 species, including the tortoise, by providing a commitment to implement specific CAs. Subsequent to the MSHCP, a site-specific conservation management strategy (CMS) is required for each of four areas in Clark County known as Desert Wildlife Management Areas (DWMAs). The intent of the CMS is to guide management actions and to unite federal, state, and local agencies in coordinated, adaptive management for each DWMA. This document is a CMS for the Coyote Springs DWMA, which encompasses the Desert National Wildlife Refuge, Coyote Springs Investment, and Coyote Springs area of critical environmental concern (ACEC), and is almost entirely preferred desert tortoise habitat of creosote- bursage vegetation on gentle plains and bajadas. Along its northern boundary, a large residential and resort development has the potential to impact conservation efforts. Construction of roads and utility rights-of-way (ROWs), as well as increased human activity, may introduce serious threats to the future viability of desert tortoise populations in the DWMA.
