This dataset represents freshwater streams on the Chugach National Forest, Alaska. Streams were digitized from 1:31,380 orthophoto quads. Estuarine channel types may extend beyond shoreline. Selected stream arcs on Cordova Ranger District updated October and November 2002. Presence of fish species and stream class were updated.
The 303(d) Listed Impaired Waters program provides impaired water data and impaired water features reflecting river segments, lakes, and estuaries designated under Section 303(d) of the Clean Water Act (CWA). Each State will establish Total Maximum Daily Loads (TMDLs) for these waters. Note the CWA Section 303(d) list of impaired waters does not represent waters that are impaired but have an established TMDL, impaired waters for which other pollution control mechanisms are in place and expected to attain water quality standards, or waters impaired as a result of pollution. Therefore, the "Impaired Waters" layers do not represent all impaired waters reported in a state's Integrated Report, but only the waters comprised...
The NetMap concept is based on standardized, contiguous digital map databases that interact with a plug & play analysis tool library (erosion, stream temperature, in-stream wood etc.) to create customizable analysis platforms for decision support in a wide range of natural resource activities. Refer to the 2009 American Geophysical Union article on “the future of applied watershed science at regional scales” for additional information (available for download at the bottom of NetMap’s home page). The uniform, contiguous and attributed stream map databases can be downloaded, and then adjusted with respect to locations of channel heads, drainage density and the length scales of stream networks (default stream segment...
Trout Unlimited developed the Conservation Success Index (CSI) in order to become more strategic and effective in our conservation efforts. Using the CSI, we can quantify and map the conservation status of all native coldwater fishes so that comparisons of existing condition, threats, future security, and management opportunities can be made across watersheds, river basins, and entire species. This enables us to deliver conservation in context. The CSI integrates population data from various assessments completed by state and federal agencies with spatial data on habitat and threats gathered by TU scientists to create a common analytical framework applicable to all coldwater fishes. The basic components of...
This theme shows the Key Watersheds that are located on BLM lands and adjacent Forest Service Lands, as identified during the Forest Ecosystem Management Assessment effort (Northwest Forest Plan - Record of Decision 1994). The initial mapping done in 1994 was a very generalized representation and was done prior to the development of the interagency standard 5th and 6th field watershed boundaries. The line work has been made coincident with the 5th and 6th field watershed lines where the Key Watershed Boundaries clearly intended to use a watershed as the boundary. District personnel have reviewed these edits to conform to the 5th and 6th field boundaries and have incorporated other edits to follow operationally identifiable...

This dataset represents the average surface runoff for each HUC5 watershed, simulated by the model MC1 for the 30-year period 1971-2000. Mean surface runoff (in mm H2O yr-1), was determined for each HUC5 watershed by averaging values of original ~ 4 km raster data. Watersheds represent 5th level (HUC5, 10-digit) hydrologic unit boundaries and were acquired from the Natural Resources Conservation Service. Background: The dynamic global vegetation model MC1 (see Bachelet et al.2001) was used to simulate vegetation dynamics, associated carbon and nitrogen cycle, water budget, and wild fire impacts for OR, WA, AZ and NM, for a project funded by the USDA Forest Service (PNW09-JV-11261900-003). The MC1 model was...
Simulated Surface Runoff Change by the biogeography model MAPSS using S. Hostetler's (USGS) climate data (detailed information available at http://regclim.coas.oregonstate.edu/domains.html), created using RegCM3 with GENMOM boundary conditions. MAPSS (Mapped Atmosphere-Plant-Soil System) is a static biogeography model that projects potential vegetation distribution and hydrological flows on a grid (http://www.databasin.org/climate-center/features/mapss-model). MAPSS has been used widely for various climate change assessments including the 2000 National Assessment Synthesis Team's report. MAPSS uses long term, average monthly climate data (mean monthly temperature, vapor pressure, wind speed, and precipitation)...

The Aquatic and Riparian Effectiveness Monitoring Plan (AREMP) characterizes the ecological condition of watersheds and aquatic ecosystems to answer the core question: “Are the Northwest Forest Plan (NWFP) and the BLM Western Oregon Resource Management Plans maintaining and restoring the conditions of aquatic and riparian ecosystems on federal lands in the Forest Plan area?” AREMP determines the status and trend of inchannel and upslope-riparian watershed condition for sixth-field watersheds (HUC12) within the NWFP area. Upslope and riparian condition are based on mapped data (e.g. road density, vegetation) for all watersheds with ≥5% federal ownership. Inchannel condition is based on stream data (e.g. substrate,...
This directory contains summaries of 30 arc-second (~800m) snow products generated using the Variable Infiltration Capacity (VIC) macroscale hydrologic model. The driving meteorological dataset was generated by downscaling the 1/16th degree data used by Littell et al. 2011 (Regional Climate and Hydrologic Change in the Northern US Rockies and Pacific Northwest, http://cses.washington.edu/picea/USFS/pub/). The downscaling to 30 arc-second was achieved using PRISM climate normals for monthly average temperature and precipitation. In addition to the increased resolution, VIC was adjusted to take gridcell mean slope and aspect as inputs to the radiative calculations. Due to space constraints, only SWE (Snow Water Equivalent,...
This cover dataset contains polygons which depict Riparian Management Areas and wind farm buffers (no cut areas) on the Tongass National Forest.
Natural Resources Canada, with assistance from the Canadian Space Agency and in collaboration with the provinces, territories and other federal agencies, has produced a unique cross-country map detailing Canada’s forested land cover. The EOSD team used all of the Landsat images that intersect with Canada’s forested ecozones, which cover about 60 percent of the country. About 80 percent of the country was mapped, and all land cover types found in those images were classified, including forest cover. At 25-metre resolution, the tiles represent the highest spatial resolution satellite-derived map data available for the total area of Canada covered. The tiles are based on Canada’s national topographic system...
Percent change in the average surface runoff for each HUC5 watershed between historical (1971-2000) and future (2071-2100) time periods. The MC1 dynamic vegetation model was run under the CSIRO, MIROC, and Hadley climate change projections and the A2 anthropogenic emissions scenario. Simulated mean annual surface runoff (in mm H2O yr-1), was determined for each HUC5 watershed by averaging values of original ~ 4 km raster data. Watersheds represent 5th level (HUC5, 10-digit) hydrologic unit boundaries and were acquired from the Natural Resources Conservation Service. Background: The dynamic global vegetation model MC1 (see Bachelet et al. 2001) was used to simulate vegetation dynamics, associated carbon and...
Simulated percent change in the average annual amount of water contributed to the stream network for each watershed between historical (1971-2000) and future (2071-2100) time periods. The MC1 dynamic vegetation model was run under the CSIRO, MIROC, and Hadley climate change projections and the A2 anthropogenic emissions scenario. Mean streamflow (stormflow + baseflow + runoff) was determined for each watershed by averaging values of original ~ 4 km raster data, and percent change was calculated as (STREAMFLOW(2071-2100) minus STREAMFLOW(1971-2000)) divided by STREAMFLOW(1971-2000). Data are from MC1 version B60. Watersheds represent 5th level (HUC5, 10-digit) hydrologic unit boundaries and were acquired from the...
Global Land Ice Measurements from Space (GLIMS) is an international project with the goal of surveying a majority of the world's estimated 160,000 glaciers. GLIMS uses data collected primarily by the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) instrument aboard the Terra satellite and the LANDSAT Enhanced Thematic Mapper Plus (ETM+), along with historical observations. The GLIMS project is currently creating a unique glacier inventory, storing information about the extent and rates of change of all the world's glacial resources. GLIMS consists of many institutions called Regional Centers, who produce glacier analyses for their particular region. The GLIMS Glacier Database provides students,...

A regional scale hydrologic simulation scheme was developed to predict stream flow and temperature...
The Monthly Projected Snow Water Equivalence (SNWE) data sets are part of the downscaled global climate models created for the 2008 California climate change assessment. These files are made from daily data and are monthly mean values in millimeters. SNWE layers have been created through a Bias Corrected Statistical Downscaling (BCSD) approach and are currently available for the cnrmcm3, gfdlcm21, ncarccsm3, and ncarpcm1 models under the A2 and B1 scenarios. The BCSD data cover 31.9375N to 43.9375N and 124.5625W to 113.0625W. The VIC grid is a 1/8th degree grid so this makes a "box" of 93 longitudes by 97 latitudes. The VIC computations are done over land only. For the 93x97 box there would be a total of 9021 points...
Climate change is projected to alter the flow regimes of streams and rivers, with consequences for physical processes and aquatic organisms. To study these hydrologic changes, we have developed a database of flow metrics for streams in the western US (extent shown on the map to the left) under historical conditions and climate change scenarios. These are based on daily simulations of the Variable Infiltration Capacity (VIC) macroscale hydrologic model produced by the University of Washington Climate Impacts Group. Trout Unlimited and the US Forest Service Rocky Mountain Research Station used these model outputs to calculate a set of summary flow metrics to describe key attributes of the flow regime for each stream...
Top conservation priorities for the coastal temperate rain forest bioregion include the protection and stewardship of large contiguous blocks of undeveloped land and water. Watersheds form a logical unit of analysis to identify such priority areas: the flow of water through a drainage basin integrates distribution of fish populations, flows of energy, and movement of materials. The analysis illustrated by this map is based on a methodology developed by Keith Moore (1991) as part of an inventory of coastal watersheds in British Columbia. The level of disturbance within the rain forest within primary coastal watersheds larger than 5,000 hectares is shown in relation to protected areas. Approximately 41 percent of...
