    ABSTRACT This inventory presents the status and usage of all permitted, certificated and claim of vested right (vested claim) groundwater rights located within the Truckee Meadows Hydrographic Basin (6-087) for water year 2012 (October 1, 2011 through September 30, 2012). The data presented are valid for the time 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 continuing basis. For water year 2012, the permitted, certificated and vested claim groundwater rights totaled 42,124 acre-feet; estimated pumpage was 19,505 acre-feet. The amount of water appropriated for municipal and quasi-municipal use (the largest appropriative manners of use in the basin) was 24,536 acre-feet, and pumpage was 13,779 acre-feet.

    NOTE: Committed groundwater resource data is accurate for October 2012. Manner of Use category totals

    vary over time, as rights are not necessarily static. Individual rights may be subject to change applications, certification, withdrawals, and cancellations; each of these circumstances could impact 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.

    *Includes pumpage by exempt domestic wells, as defined by NRS 534.013. The domestic use estimate is based upon a count of the total number of improved lots not served by Washoe County Utilities in the basin multiplied by 1.0 acre-foot per annum. The number of active domestic wells on improved lots in the basin as estimated utilizing information supplied by Washoe County’s Health Department is 1,742.

    ** Domestic total includes active domestic water rights (117 AFA).

    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. The estimated amount of groundwater pumped under permits, certificates, vested claims, and exempt domestic wells within the Truckee Meadows Hydrographic Basin (6-087), for the time period beginning October 1, 2011 and ending September 30, 2012 (herein referred to as water year 2012) is described in the following sections.

    DESCRIPTION OF THE STUDY AREA

    The Truckee Meadows Hydrographic Basin is located in northwest Nevada and lies

    wholly within the state. The basin occupies approximately 204 square miles in Washoe County. The adjacent hydrographic basins are Truckee Canyon Segment (6-091) to the west; Lemmon Valley Eastern Part (07-092B), Sun Valley (6-086) and Spanish Springs Valley (6-085) to the north; Tracy Segment (6-083) and Dayton Valley (8-103) to the east; and Washoe Valley (6-089) and Pleasant Valley (6-088) to the south. The boundary of the Truckee Meadows Hydrographic Basin is described by Designation Order 708, issued by the Nevada State Engineer and dated March 1, 1978.

    The Truckee Meadows Hydrographic Basin is bounded on the west by the Carson Range, on the northwest by Peavine Peak, on the east by the southern extension of the Pah Rah Range and by the Virginia Range, and on the south by the Steamboat Hills. The northern boundary of the basin coincides with the administrative basin boundary lines of Lemmon Valley, Sun Valley and Spanish Springs Valley. The valley is approximately 11 miles wide by 13 miles long. Elevations range from 10,776 feet (all elevations in this report are above mean sea level) at Mount Rose, in the southwest corner of the basin, to less than 4,400 feet near Reno-Tahoe International Airport.

    HYDROLOGY

    The dominant hydrologic features of the Truckee Meadows Hydrographic Basin are the

    Truckee River and major irrigation ditches that transport water around the region. The Truckee River flows from its headwaters in the Sierra Nevada, through Lake Tahoe, the Truckee Meadows, the Vista Narrows and Dodge Flat, to its terminus at Pyramid Lake. Within the basin, the major tributaries to the Truckee River are Steamboat Creek, Thomas Creek, Whites Creek, Hunter Creek, Evans Creek, Dry Creek and Peavine Creek. The Truckee River enters the basin at an elevation of approximately 4,700 feet near Mogul, flows generally west to east over a distance of approximately 13 miles, and exits the basin at an elevation of approximately 4,395 feet near Vista.

    METHODS TO ESTIMATE PUMPAGE

    This report estimates the amount of groundwater pumped under vested claims and the permits and certificates issued by the State Engineer, as well as the amount pumped by domestic wells in the valley. 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 data.

    • Where meters were not in place and the manner of use was irrigation, pumpage was estimated by multiplying the number of hours the well was operated during the past year (determined from an hour meter reading or asking the water user) by the certificated diversion rate.

    • Where meters were not in place, the manner of use was irrigation, and the number of hours the well was operated was unknown, the place of use was inspected to estimate the amount of acreage under cultivation. The number of acres under cultivation was then multiplied by a duty of 4 acre-feet per acre to estimate the pumpage.

    • Where meters were not present, previous data not available and the manner of use was not irrigation, pumpage was estimated by applying the annual duty associated with the certificate, permit or vested claim, if the use was as described in the certificate, permit or vested claim. If the use was not as described in the certificate, permit, or vested claim, pumpage was estimated based upon the circumstances of use.
