Ecologically relevant river size classes for NHDPlus v1 flowlines in the 14 state SARP region. Size class was determined for each river flowline using the cumulative drainage area from NHDPlus v1 dataset. The data are scaled to show the largest rivers at the regional scale. Zoom into the map for smaller rivers, creeks, and headwaters. For more information about how this attribute was developed by the Southern Instream Flow Network (SIFN), go to http://www.southeastaquatics.net/sarps-programs/sifn/instream-flow-resourcesYour comments about this dataset are welcome. Please send comments to the dataset author using the Comment tab below.Â

The SARP Riparian Assessment analysis assesses the current condition of riparian habitat within a 30 meter buffers along streams and rivers throughout the SARP region and provides a baseline against which to measure future progress toward achieving riparian habitat conservation/restoration goals.

This geodatabase contains the official boundary of the Southeast Aquatic Resource Partnership with State Boundaries. The boundary was originally developed by the United States Fish and Wildlife Service and was updated in 2020 to reflect revisions from the Southeast Aquatic Resource Partnership, a recognized Fish Habitat Partnership (FHP) of the National Fish Habitat Partnership.

Risk of altered ecologically significant components of the flow regime due to human impacts. The SARP Flow Alteration Assessment provides a regional characterization of the distribution and risk of altered flow regimes at the NHDPlus segment scale. The human impacts include runoff from impervious surfaces, evaporative losses from artificial water bodies, and surface water use. Impacts of these activities on selected ecologically significant components of the flow regime are given in the attached document. These flow components...
This map depicts the Rivers and Streams Conservation Asset for Florida with road barriers from the Southeast Aquatic Barriers Tool. The number of miles that could be gained through conservation action to remove obstructions are summarized by HUC12 watershed units. River/Stream Connectivity is an ecological indicator for the Landscape Conservation Project for Florida. The project entails a large-scale assessment of and planning for the health of important natural resources, known as Conservation Assets (CAs), in Florida. Conservation planning at the landscape scale provides a framework for safeguarding functional ecosystems, and their interconnected processes necessary to achieve true preservation of healthy resources....

Maps of priority conservation areas were obtained for DOI and USFS protected lands, state wildlife action plans, SARP regional threat assessment maps, TNC ecoregional portfolios (see map on left), and others. Conservation status was assigned to NHD+ river segments. The Aquatic Conservation Area report to the SALCC documents attempts to designate a single set of priority areas from these resources (see link below). Due to inconsistencies in the objectives and methods used to designate priority areas among states and other groups, the effort was not successful for the SALCC. Another attempt will be made for the GCPLCC project.  For more detailed information, go to the SIFN page on the SARP website at http://www.southeastaquatics.net/sarps-programs/sifn
The SARP Flow Alteration Assessment provides a regional characterization of the distribution and risk of flow regime impairment of streams and rivers by anthropogenic sources at the NHD+ segment scale. This map illustrates the cumulative risk of flow alteration (RFA) from surface water use for thermopower generation in Oklahoma.  Water use is based on state permits for surface water withdrawals and returns.  The risk is based on the volume of water used monthly in the drainage area relative to the monthly volume of flow.  Risk of Flow Alteration categories:  ZERO     - 0% mean monthly flow depletion,  LOW      - > 0-10%,  MEDIUM - > 10-20%,  HIGH      - >20-100%, and  PROVISIONAL...
River classification by months of high and low flow and range of variability.  Original gage point data was extrapolated to near by areas using the Watershed Boundary Dataset, the Baseflow Index grid, gage data, and expert review.For more information about the hydrologic classes and how this attribute was developed for the Southern Instream Flow Network (SIFN), go to attached report or visit http://www.southeastaquatics.net/sarps-programs/sifn/instream-flow-resources.  Your comments about this map and the attribute databases are welcome. Please send comments to the map author using the comment tab below.
Ecoregions of the SARP region based on Omernik (1987) attributed to NHDplus catchments. Ecoregions are areas with generally similar ecosystems and similar types, qualities, and quantities of environmental resources,. Ecoregion boundaries were determined by examining patterns of vegetation, animal life, geology, soils, water quality, climate, and human land use, as well as other living and non-living ecosystem components. Level IV ecoregions are delineated at the local scale.For more information about this attribute, visit http://www.epa.gov/wed/pages/ecoregions.htm and http://nationalatlas.gov/mld/ecoomrp.html.

Fresh and Saltwater Connectivity This layer was one of the old South Atlantic LCC indicators in the waterscapes ecosystem. It was an index of dams preventing fish migration between rivers and the ocean. Fresh and saltwater connectivity was not performing well as an indicator and could not be used in Blueprint 2.0. This indicator was replaced in Blueprint 2.1 with a new migratory fish connectivity indicator. Reason for Selection Barriers to connectivity between rivers/streams and the ocean can strongly impact diadromous fish and alter natural movement of sediments, are easy to monitor and model, and are widely used and understood by diverse partners.
