This dataset contains small cutthroat trout lakes within Southeast Alaska. These are smaller lakes that do not produce cutthroat trout large enough to reach the 11-inch regional minimum size limit. Each of these lakes has a 9-inch minimum size limit, and bait is prohibited. Regionwide limits of 2 per day and 2 in possession apply. Currently there are seven lakes in Southeast Alaska with the small cutthroat lake designation. Please verify fishing regulations with current Alaska Department of Fish and Game Sport Fishing Regulations at the following link: http://www.adfg.alaska.gov/index.cfm?adfg=fishregulations.se_sportfish

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...

Project Summary Climate change is projected to have substantial impacts on Pacific Northwest water resources and ecosystems. Recognizing this, resource managers have expressed growing interest in incorporating climate change information into long-range planning. The availability of hydrologic scenarios to support climate change adaptation and long-range planning, however, has been limited until very recently to a relatively small number of selected case studies. More comprehensive resources needed to support regional planning have been lacking. Furthermore, ecosystem studies at the landscape scale need consistent climate change information and databases over large geographic areas. Products using a common set of...

The Monthly Projected Baseflow (BASF) 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/month. BASF 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 and...

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...

The Alaska Department of Fish and Game's (ADF&G) Anadromous water bodies data is derived from the ADF&G's GIS shape files for the "Catalog of Waters Important for Spawning, Rearing or Migration of Anadromous Fishes" (referred to as the "Catalog") and the "Atlas to the Catalog of Waters Important for Spawning, Rearing or Migration of Anadromous Fishes" (referred to as the "Atlas"). It is produced for general visual reference and to aid users in generating various natural resource analyses and products. The shape files depict the known anadromous fish bearing lakes and streams within Alaska (from the mouth to the known upper extent of species usage). It incorporates data from a variety of sources including:...

Our monitoring effort determines watershed condition every five years for every 6th-field watershed (with > 25% federal ownership along the stream length) based on upslope and riparian data derived from GIS layers and satellite imagery. In-channel attributes are also measured each year in a subset of watersheds to supplement the watershed condition assessments and validate the models used to assess stream condition. Watershed condition assessments are done using decision-support models (see EMDS Overview). AREMP also tracks changes in watershed condition over time; and reports on the Forest Plan's effectiveness across the region. The results reported here are for the approximately twenty 6th field sub-watersheds...

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,...

Here we describe one conservation tool that will help to identify particularly significant river basins of the North Pacific for the conservation of salmon: the first Pacific-Rim wide assessment of salmon populations at a consistent scale. In conjunction with a scientific advisory panel and a peer review workshop we developed four criteria for the Pacific Salmon Conservation Assessment (PSCA) to provide an indication of aquatic ecosystem and salmon population resilience at the basin scale. These criteria are salmon abundance, diversity, hatchery influence, and landscape suitability. Highly abundant salmon populations have more “cushion” with which to absorb anthropogenic or natural disturbance (Quigley and...

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,...

The NPR basins were ranked according to regional patterns of environmental stress for salmon under current and projected future (to 2100) climate conditions. The basin rankings account for the relative abundance and distribution of freshwater habitats in each basin and include dynamic river flow and temperature simulations as indicators of water quality. A salmon stress index was developed based on temperature thresholds for spawning, incubation, and rearing for individual salmon species. The salmon stress ranking was coupled with the sub-watershed physical complexity ranking to develop a watershed vulnerability index for individual salmon species. Chinook and Coho rankings are highlighted below Each variable was...
