Grand Lake Extent 1830

These data represent the approximate delineation of land and water in the area of Grand Lake in the Atchafalaya basin in the early 1800s. These data are based on a georectified map of the original township surveys conducted between 1807 and 1838. The composite township survey map was created in 1948 and was obtained from the Louisiana State Lands Office in Baton Rouge, LA. The composite township survey map was georectified using airphots and lidar to current landforms using ERDAS Imagine. The delineation of land and water was conducted using Adobe Photoshop, and was restricted to an arbitrarily defined area that captured most of the former extent of Grand Lake. The resolution of the original delineation was 3x3m and was ressampled to 30x30m in this application for comparison to modern data sources These data represent the approximate delineation of land and water in the area of Grand Lake in the Atchafalaya basin in the early 1800s.

The Atchafalaya Basin is a resource that must be managed on a system-wide basis to ensure this invaluable national resource is protected and restored. It is recognized that better tools must be developed for managing the Basin and that data evaluation is necessary to ensure sound decision-making. The natural resource inventory and assessment system (NRIAS) that was approved and funded in the FY 2010 Louisiana Department of Natural Resources Atchafalaya Basin Program Annual Plan and served as the primary tool for decision making in the Basin. The system provided a means for scientists to access relevant project data for the Basin and to request and fund data acquisition, monitoring, and data analysis to be used in project planning. This will be critical in providing information necessary for the development and approval of specific projects to be included for construction in future Annual Plans, projects that meet the needs of Louisiana citizens and protect our our natural resources. This and related datasets were created to demonstrate the patterns of inundation, turbid water and floating aquatic vegetation in the Atchafalaya Basin Floodway System at various river levels of the Atchafalaya River.

VIEW_MAINE_ACJV Coastal Marsh Project Database

This map shows the locations of the Atlantic Coast Joint Venture (ACJV) project database, which catalogs salt marsh restoration, management, and enhancement projects along the coast. The projects support salt marsh conservation, including efforts specifically targeting the ACJV flagship species: Saltmarsh Sparrow, Black Rail, and American Black Duck. For more information, please visit: [https://acjv.org/tools-and-data/] The urgent need for coordinated attention and our shared responsibility for coastal marsh conservation prompted the ACJV Management Board to approve a strategic focus on coastal marsh habitat carried out through the lens of our three flagship species: American Black Duck, Black Rail, and Saltmarsh Sparrow (link). ACJV partners are developing a comprehensive conservation planning framework to address the needs of these three species and the ecosystems upon which they depend.
06062022 Dam Diversion Survey

This is the feature service linked to the survey123 survey used by those surveying diversions and their structures for aquatic organism passage within inland waters (non-tidal). Diversions often contain a low-head dam type of structure and a diversion ditch/channel. This form is designed to collect information on both types of elements of a water diversion. The data collected within this form is used in SARP's Aquatic Barrier Prioritization Tool (https://connectivity.sarpdata.com). This data layer can be used to better understand the specific information associated with fish passage including photos for points surveyed Water diversions are points along a stream where water is diverted from the free flowing stream into nearby fields. To divert water, irrigators will dig a ditch along the stream and often build an in stream dam/structure to impound the water so it flows into the ditch. Not only can fish and other organisms not pass upstream, but they can get caught in ditches and be trapped, unable to get out. These diversions present issues for species in aquatic systems and identifying their location aids in identifying potential restoration projects and landowner partnership opportunities.

Lake Watersheds from LAGOS-LOCUS Data

Data are directly from the [LAGOS-US platform]. The current dataset identifies the lake watershed: the contributing watershed area accumulated upstream to the first connected lake ≥ 10 ha, if present. This definition emphasizes the importance of local inputs, and also acknowledges the potential for larger upstream lakes to function as sinks. The LAGOS-US dataset contains locational, identifying, and physical information of all lakes ≥ 1 ha and their watersheds in the conterminous U.S. Geospatial files for lakes and watersheds as well as tables for linking across other LAGOS modules and broad-scale lake databases are available. LOCUS data can be linked across LAGOS data products using the unique lake identifier (lagoslakeid).

Red_AWC_FBN_Kake_

This comprehensive data layer provides an updated inventory of water crossing structures in the Kake area, compiled in 2024. This modified version of Bob Christianson's original dataset includes binary attributes for filtering and SQL versioning for webmap usage. This data layer is designed for use by resource managers, conservationists, and transportation planners involved in fish habitat restoration and infrastructure development. It serves as a valuable resource for assessing the impacts of water crossings on fish passage, prioritizing maintenance activities, and informing future infrastructure projects.
Reservoir subset joined to LAGOS lakes dataset

This layer represents a subset of the Reservoir Fish Habitat Partnership data (https://fishhabitat.org/the-partnerships/reservoir-fisheries-habitat-partnership) joined to LAGOS lakes data (https://lagoslakes.org/lagos-research-platforms/) and 2021 National Landcover data (https://www.mrlc.gov/data). The values for "totdev_totag21" represents the percentage of landcover identified as "agriculture" or "developed" in the upstream lakes watersheds (watersheds as defined by LAGOS lakes dataset). This product is intended to be used for a one time evaluation of the two sources of lake quality. Please contact yvonne_allen@fws.gov for further details about this comparison.
FWS American Woodcock Singing Ground Survey Zones

The American woodcock (Scolopax minor) is a popular game bird throughout eastern North America. The management objective of the U. S. Fish and Wildlife Service (FWS) is to increase populations of woodcock to levels consistent with the demands of consumptive and non-consumptive users ([U. S. Fish and Wildlife Service 1990]). Reliable annual population estimates, harvest estimates and information on recruitment and distribution are essential for comprehensive woodcock management. Unfortunately, this information is difficult and often impractical to obtain. The American Woodcock Singing-ground Survey was developed to meet part of these information needs by monitoring changes in annual abundance indices. This map depicts latitude line boundaries that assist Woodcock Singing Ground Survey (SGS) participants in determining which survey window their route falls within. The survey window determines when the route can be run on an annual basis. More information on the Woodcock SGS can be found at this link: [https://www.fws.gov/project/american-woodcock-singing-ground-survey] The archived version of this file can be found here: <[ServCat Link]> This dataset is documented in data management plan here (internal access only). <[DMP Link]>

FWS R2 ES Bexar County Karst Invertebrate Critical Habitat

Critical Habitat was designated in 2012 for areas known to be occupied by any of the federally endangered karst invertebrates in Bexar County, Texas. These Critical Habitat Units (CHUs) include the cave footprint, surface and subsurface drainage areas of the cave (where known), a cave cricket foraging area, and an area of at least 100 acres around the cave footprint of undisturbed or restorable vegetation as recommended by the Bexar County Karst Invertebrates Recovery Team. In this designation, the Service included areas that possess those physical or biological features essential to the conservation of each of the species and that may require special management consideration or protection. Even though karst invertebrates spend their entire lives underground, the Service included specific surface features when identifying CHUs, given they are important drainage links into the caves, and because surface habitat is needed to support the plant and animal communites upon which karst invertebrates depend for nutrients.
LiDAR_Nantahala_MaxDrop15plus_3rdOrderPlus

This dataset is a dataset of modeled waterfall points using LiDAR in partnership with Trout Unlimited. These points were hand verified by students to determine if waterfalls could be seen at these sites using aerial imagery. These are points on stream order of 3 or greater, with a drop of 15 feet or greater. This effort is a first step to detecting undocumented falls and dams using LiDAR in the United States, so that they can be added to the National Aquatic Barrier inventory at aquaticbarriers.org, an effort led by the Southeast Aquatic Resources Partnership and NFHP. This inventory is a part of a larger effort called the National Aquatic Connectivity Collaborative that seeks to identify all man-made aquatic barriers across the country.
