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...
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 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,...
Data Format ‐Temperature and discharge output file is in csv format. Data Units ‐Temperature – Degrees Celsius, Discharge – Cubic Meters per Day ‐The data is organized as followed: Pixel Location – Lat, Long Catchment – name of RAP catchment the pixel belongs to Date – Julian day Temperature – T_Historic, T_2020s, T_2040s, and T_2080s Discharge – Q_H(Historic), Q_2020s, Q_2040s, and Q_2080s Distributed hydrologic modeling is an important tool for quantifying dynamic environmental constraints (river flow and temperature) on stream habitat quantity, quality and distribution as they may be affected by climate change. 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...
These data are intended for use in a variety of applications where fish distribution and activity is important. Note that the StreamNet database contains distribution information for numerous species. Within the source database, overlap does not exist for a particular species/run/subrun combination. See information under the spatial process log for specific information regarding the query that was used to construct this particular feature class.

Effects of changes in hydrologic regimes on anadromous fish,
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...
