Province-wide SDE spatial view displaying dam locations. The public view displays a subset of the attribute data
This project will address species-habitat relationships for a priority aquatic system for the GCPO LCC, Mainstem Big Rivers. Specifically, the project will collect subsurface aquatic habitat data using side-scan sonar and high resolution bathymetry data in the Pearl River system of Louisiana. This project expands on current work ongoing in the Pearl River, and would extend habitat data collection for the purposes of making recommendations on restoration of aquatic habitat for species endpoints in this aquatic system. This project directly addresses landscape conservation design and will be used to inform Adaptation Strategies.

NOTE: This download link includes Fish Regions, Freshwater Ecoregions, and Freshwater Resilience. Freshwater ecoregions provide a global biogeographic regionalization of the Earth's freshwater biodiversity. These units are distinguished by patterns of native fish distribution resulting from large-scale geoclimatic processes and evolutionary history. The freshwater ecoregion boundaries generally, though not always, correspond with those of watersheds. Within individual ecoregions there will be turnover of species, such as when moving up or down a river system, but taken as a whole an ecoregion will typically have a distinct evolutionary history and/or suite of ecological processes (Abell et al. 2008). The WWF defined...

Resilient stream systems are those that will support a full spectrum of biodiversity and maintain their functional integrity even as species compositions and hydrologic properties change in response to shifts in ambient conditions due to climate change. We examined all connected stream networks in the Northeast and Mid-Atlantic for seven characteristics correlated with resilience. These included four physical properties (network length, number of size classes, number of gradients classes and number of temperature classes), and three condition characteristics (risk of hydrologic alterations, natural cover in the floodplain, and amount of impervious surface in the watershed). A network was defined as a continuous...

The download for this dataset includes TNC’s full Northeastern Aquatic Habitat Classification System: stream size, stream temperature, stream gradient, stream geology, lakes and catchments. This dataset represents the results (9/30/2008) of the Northeastern Aquatic Habitat Classification System (NAHCS) GIS map for streams and rivers. This classification focused on mapping a stream habitat types across 13 northeastern states (ME, NH, VT, MA, CT, RI, NY, NJ, PA, MD, DC, DE, VA, WV). Stream and river centerlines were extracted from the USGS National Hydrography Dataset Plus (NH-Plus) 2006 1:100,000 data. These reaches were attributed and placed into classes representing their biopysical setting in terms of stream...

The National Hydrography Dataset (NHD) is a feature-based database that interconnects and uniquely identifies the stream segments or reaches that make up the nation's surface water drainage system. NHD data was originally developed at 1:100,000-scale and exists at that scale for the whole country. This high-resolution NHD, generally developed at 1:24,000/1:12,000 scale, adds detail to the original 1:100,000-scale NHD. (Data for Alaska, Puerto Rico and the Virgin Islands was developed at high-resolution, not 1:100,000 scale.) Local resolution NHD is being developed where partners and data exist. The NHD contains reach codes for networked features, flow direction, names, and centerline representations for areal water...

The dataset represents the work of multiple states and Federal agencies as part of the US Gap Analysis and LandFire programs. Multi-season satellite imagery (Landsat ETM+) from 1999-2001 were used in conjunction with digital elevation model (DEM) derived datasets (e.g. elevation, landform) to model natural and semi-natural vegetation. The minimum mapping unit for this dataset is approximately 1 acre. Landcover classes are drawn from NatureServe's Ecological System concept. Five-hundred and fourty-four land cover classes composed of 12 cultural and 532 Natural/Semi-natural types are described. Land cover classes were mapped with a variety of techniques including decision tree classifiers, terrian modeling, inductive...

This dataset provides an estimate of aquatic biodiversity sites, based on protected and conservation lands superimposed on the NHD flowlines dataset. Caution is warrented in interpreting this dataset. While measures of aquatic biodiversity exist, they are based on localized samples that cannot be extrapolated beyond the sampling domain. These measures were not included in this dataset. Instead, it was assumed that areas within TNC Portfolio areas were identified for factors that include high aquatic biodiversity. Furthermore, it is assumed that aquatic biodiversity is higher in protected areas due to stricter controls over land and water management. However, this assumption may not be valid for stream reaches that...

WRPOD is a point coverage created weekly from data in the Utah Division of Water Rights database. It contains water right point of diversion information. This dataset was retrieved from http://www.waterrights.utah.gov/gisinfo/wrcover.asp on 10/31/2011.

This dataset provides an estimate of water-based recreation travel corridors, based on a combination of wild and scenic rivers, and major rivers selected from NHD that were listed on the BLM rivers website. All reaches of these rivers were selected, as insufficient information exists to determine what segments may or may not be open to recreation. Other areas may be open to water-based recreation travel than are represented in this dataset.

The National Hydrography Dataset (NHD) and Watershed Boundary Dataset (WBD) are used to portray surface water on The National Map. The NHD represents the drainage network with features such as rivers, streams, canals, lakes, ponds, coastline, dams, and streamgages. The WBD represents drainage basins as enclosed areas in eight different size categories. Both datasets represent the real world at a nominal scale of 1:24,000-scale, which means that one inch of The National Map data equals 2,000 feet on the ground. To maintain mapping clarity not all water features are represented and those that are use a moderate level of detail. The NHD and WBD are digital vector datasets used by geographic information systems (GIS)....
