GBI - Weed Mapping in Truckee River Floodplain

The Great Basin Institute mapped 12 species of weeds in the Truckee River floodplain during the summer of 2008.

The species mapped are as follows: (the map uses a 4 letter code)

  • Yellow starthistle (Centaurea solstitialis)
  • Russian knapweed (Acroptilon repens)
  • Spotted knapweed (Centaurea maculosa)
  • Diffuse knapweed (Centaurea diffusa)
  • Scotch thistle (Onopordum acanthium)
  • Musk thistle (Carduus nutans)
  • Tamarisk (Tamarix ramosissima, etc.)
  • Purple loosestrife (Lythrum salicaria)
  • Hoary cress (Cardaria draba)
  • Tall whitetop (Lepidium latifolium)
  • Medusahead (Taeniatherum caput-medusae)
  • Canada thistle (Cirsium arvense)
  • Rush skeletonweed (Chondrilla juncea)
  • Dalmatian toadflax (Linaria dalmatica)
  • Yellow toadflax (Linaria vulgaris)

USDA - NRCS soils mapping tool

The Soil Data Mart allows you to:

-Determine where soil tabular and spatial data is available.
-Download data for one soil survey area at a time. (Download requests for more than one survey area at a time can be submitted through the Geospatial Data Gateway. Going through the Geospatial Data Gateway also provides the option to obtain data on CD or DVD.)
-Download a template Microsoft Access® database for working with downloaded data.
-Generate a variety of reports for one soil survey area at a time.
-Find out who to contact for information about soil data for a particular state.
-"Subscribe" or "unsubscribe" to a soil survey area. A person who is subscribed will automatically be notified whenever data for that soil survey area is updated. You must register and login before doing this.

Pluvial Lake Lahontan

During the Pleistocene era, a large lake persisted in what is now the Great Basin. During this epoch, climactic conditions existed such that, there were periods of higher precipitation and considerably less evaporation than modern day. This created a large inland body of water (Lake Lahontan) in the western portion of the Great Basin. Lakes formed in this way are known as Pluvial lakes. Lake Lahontan connected many of the interior valleys within Nevada with water. This lake eventually dried up as the result of climate change, and now the remnants are today expressed as Pyramid and Walker Lakes.

City of Reno, Nevada - Watershed Mapserver


The City of Reno (and the Truckee Meadows Stormwater Committee) has provided watershed assessments as photo-documented field surveys, for the entire Truckee Meadows watershed. These are provided in an interactive mapserver, where you can click on either your region or creek of choice, in the Truckee Meadows. There are photos, descriptions of the creek reach conditions, and recommendations for restoration and watershed protection for each creek posted. Restoration will be an important component of integrated watershed management as our resources come under greater pressure through utilization, and tools are needed to evaluate priority sites to reduce loads of contaminants in the river.

Creeks and their information can be accessed by turning on navigation tools, once within the server. Watershed assessment information may be accessed two ways: through the name of the creek (top of site, choose "select creek") or by geographical area (top of site, choose "select region"). Within each creek page are photos, and by rolling over the blue buttons indicating sites of assessments, you'll uncover textual descriptions of the reaches, and tips for specific ways to restore that creek or protect waterways throughout our watershed.

USGS Truckee River Gage Stations

This data layer consists of the USGS Surface Water Gage Stations that are located within the study area of the Truckee River Information Gateway (TRIG). The coordinates are taken directly from the USGS station information webpage. The data collected from these gages is used in the sources and loadings analyses component of the TRIG project.

USGS Truckee River Watershed Shapefile

This data is a subset of the United States Geological Survey (USGS) watershed data layer, consisting of the Truckee river Watershed, delineated by Hydrologic Unit Code (HUC). This watershed boundary defines the original study boundary of the TRIG program and associated analyses.

TMWRF - Monitoring Stations Shapefile

This point shapefile shows the sample sites from the ongoing Truckee Meadows Water Reclamation Facility (TMWRF) Truckee River monitoring effort. The shapefile is in GCS_North_American_1983 (latitude-longitude), North American Datum of 1983.

NDEP - Monitoring Stations Shapefile

This point shapefile shows all sample sites from the Nevada Division of Environmental Protection (NDEP) compilation of monitoring stations in the Truckee River Basin. This includes NDEP and Desert Research Institute (DRI) monitoring stations, as well as special study and miscellaneous sites. To view long term monitoring sites and special study sites separately, please refer to Maps and GIS section, titled "NDEP Monitoring Sites and Special Sites map images".

This shapefile is in GCS_North_American_1983 (latitude-longitude), North American Datum of 1983.

NDEP - Study Area Waterbodies

This is a polygon shapefile of the waterbodies in the Truckee watershed area. It is a subset of the Nevada Division of Environmental Protection (NDEP) shapefile of Nevada waterbodies.

Washoe County's Online Map Warehouse

Online Maps of Washoe County...this is a very interactive site with lots of data! The nature of the huge volume of information here makes the navigation a bit of a process. Upon entering this site, every layer you want to view must be selected, and the direction keys or the hand pulling the map may need to be used to find the area you're looking for.
