New USGS Maps for Nevada Include Trails

Posted [by USGS]: 11 Feb 2015 06:00 AM PST

Summary: Newly released US Topo maps for Nevada now feature selected trails. The data for the trails is provided to the USGS through a nation-wide “crowdsourcing” project managed by the International Mountain Biking Association (IMBA)

Contact Information [at USGS]:
Mark Newell, APR ( Phone: 573-308-3850 ); Larry Moore ( Phone: 303-202-4019 );

Newly released US Topo maps for Nevada now feature selected trails. The data for the trails is provided to the USGS through a nation-wide “crowdsourcing” project managed by the International Mountain Biking Association (IMBA). Several of the 1,785 new US Topo quadrangles for the state now display public trails along with other improved data layers such as land survey information (PLSS), map symbol redesign and new road source data.

“Users of the US Topo maps in our state are excited about the release of these new versions,” said Carol Ostergren, The National Map Liaison for Nevada. “Nevada features numerous trails, so the addition of several mountain bike trails will increase the use of the new US Topo maps. Also, adding PLSS will assist many of our users who have been asking for that data for a long time.”

For Nevada residents and visitors who want to explore the stunning desert landscape on a bicycle seat or hiking shoes, the new trail features on the US Topo maps will come in handy. During the past two years the IMBA, in a partnership with the MTB Project, has been building a detailed national database of mountain bike trails. This activity allows local IMBA chapters, IMBA members and the public to provide trail data and descriptions through their website.  MTB Project and IMBA then verify the quality of the trail data provided and ensure accuracy and confirm that the trail is legal.  This unique crowdsourcing venture has increased the availability of trail data available through The National Map mobile and web apps, and the revised US Topo maps.

Another important addition to the new Nevada US Topo maps is the inclusion of Public Land Survey System data. PLSS is a way of subdividing and describing land in the United States. All lands in the public domain are subject to subdivision by this rectangular system of surveys, which is regulated by the U.S. Department of the Interior.

These new maps replace the first edition US Topo maps for Nevada and are available for free download from The National Map, the USGS Map Locator & Downloader website , or several other USGS applications.

To compare change over time, scans of legacy USGS topo maps, some dating back to the late 1800s, can be downloaded from the USGS Historical Topographic Map Collection.

The Graduate Program of Hydrologic Sciences Spring 2015 Colloquium—March 6: Hydrologic Modeling…Walker River Basin

What: The Graduate Program of Hydrologic Sciences Spring 2015 Colloquium
When: Friday, March 6, 2015 (4 p.m. – 5 p.m.)
Speaker: Dr. Greg Pohll
, Desert Research Institute
Title: Hydrologic Modeling Tools for the Upper Walker River Basin
DMS 110 on the UNR campus:

Abstract: The Walker Basin Restoration Program was established by Congress as part of Public Law 111-85 in October 2009. The Program’s core purpose is to restore and maintain Walker Lake, a natural desert lake in Nevada at the terminus of the Walker River stream system of Nevada-California. Walker Lake is critical to recovery of the threatened Lahontan cutthroat trout (LCT) and is an important stopover for common loons and other migratory birds. However, many decades of depleted freshwater inflows have resulted in declines of lake elevation and increases in lake salinity, which today threaten its complete ecological collapse. In order to reverse Walker Lake’s decline, the National Fish and Wildlife Foundation (NFWF) seeks to increase instream flows to Walker Lake through a comprehensive basin-wide strategy that includes voluntary water transactions and water management initiatives. A key element to the restoration program is the development of numerical tools that can simulate the hydrologic system within the basin. A variety of hydrologic models have been created to simulate the important relationships among climate, crop demand, river flows, groundwater-surface water exchange along the river and delivery ditches, irrigation practices, groundwater pumping, and all known existing water rights in both Mason and Smith Valleys. This presentation highlights the numerical tools including results showing the impacts of hypothetical water transfers on the river and groundwater systems.

The Graduate Program of Hydrologic Sciences Spring 2015 Colloquium

Seminars will be 4:00 to 5:00 p.m. in the Redfield Auditorium in Davidson Math and Science Center (DMS 110) unless otherwise noted*. An informal social will follow each seminar in the Redfield foyer outside the auditorium.

NPGS Dinner Meeting—March 5 (RSVP by March 3, TODAY): Icelandic and The Geysers Geothermal Systems

NPGS logo

What: Nevada Petroleum & Geothermal Society Monthly Dinner Meeting
Thursday, March 5, 2015
Speaker: David Boden, PhD., Professor of Geosciences, Truckee Meadows Community College
Title: Some Observations from Visiting Icelandic and The Geysers Geothermal Systems

Come to the Reno Ramada and learn about Dr. David Boden’s visit to Iceland and The Geysers! Iceland’s geothermal energy provides about 26% of its power (the balance provided by hydroelectric plants) and the space heating and hot water needs of about 88% of all buildings in Iceland (about 98% in Reykjavik). The Geysers, located about 75 miles north of San Francisco, CA, is the world’s foremost developed geothermal resource spread over about 45 square miles and hosting 15 power plants. It is also the world’s largest vapor- or steam-dominated geothermal resource that during the late 1980s and early 1990s produced as much as 2000 MW of power.

Where: Ramada Reno Hotel; 6:30 PM
1000 East 6th Street, Reno, NV 89512

Details: Open Bar 6:30 pm, Skyline Room 14th Floor
Dinner Served at 7:00 PM
