Description: Texas has approximately 196 major reservoirs. This layer depicts the existing polygons for the major reservoirs found in the State of Texas as defined by the Texas Water Development Board. Major reservoir being defined as an impoundment that currently has at least 5,000 acre-feet of storage capacity at its normal operating level. Texas has 188 major water-supply reservoirs, and over 20 additional major reservoirs that serve no water-supply function. The major reservoirs of the state vary in size from 5,200 acre-feet conservation storage capacity for the Upper Nueces Lake to 4,472,900 acre-feet for the Toledo Bend Reservoir, which includes both the Louisiana and Texas portions of the reservoir. Making the best use of existing reservoirs, controlling watershed erosion to maintain their holding capacity, and identifying viable sites for new reservoirs are key to effective long-term water supply management and planning in Texas. Please note, all impaired reservoirs, as defined by TCEQ have been added as a separate layer.This layer depicts major reservoirs within the GPLCC boundary.

Description: Strategic conservation planning for broad, multi-species landscapes benefits from a data-driven approach that emphasizes persistence of all priority species’ populations and utilized landscapes, while simultaneously accounting for human uses. This dataset represents one of many assessments for priority fishes of Texas and of the Great Plains of the United States. The spatial units represented by this dataset are intended to indicate Native Fish Conservation Areas (NFCAs) for Texas and the Great Plains. Two separate analyses went into building these NFCA units. For Texas, the analysis report can be found here: https://repositories.lib.utexas.edu/handle/2152/32905 and for the Great Plains NFCAs, the report can be found here: https://repositories.lib.utexas.edu/handle/2152/27744

Description: Landscape Conservation Cooperatives (LCCs) are public-private partnerships composed of states, tribes, federal agencies, non-governmental organizations, universities, international jurisdictions, and others working together to address landscape and seascape scale conservation issues. LCCs inform resource management decisions to address broad-scale stressors-including habitat fragmentation, genetic isolation, spread of invasive species, and water scarcity-all of which are magnified by a rapidly changing climate.Date uploaded: Wed Jan 23 11:01:40 MST 2013

Description: Saltcedar (T.ramosissima) is an invasive plant species that invades stream banks, sandbars, lake margins, wetlands, moist rangelands, and saline environments. It can crowd out native riparian species, diminish early successional habitat, and reduce water tables and interferes with hydrologic process. Point data of T.ramosissima was selected and downloaded as a shapefile from EDDMapS.EDDMapS is a web-based mapping system for documenting invasive species distribution. It is fast, easy to use and doesn't require Geographic Information Systems experience. EDDMapS combines data from other databases and organizations as well as volunteer observations to create a national network of invasive species distribution data that is shared with educators, land managers, conservation biologists, and beyond. Launched in 2005 by the Center for Invasive Species and Ecosystem Health at the University of Georgia, it was originally designed as a tool for state Exotic Pest Plant Councils to develop more complete distribution data of invasive species.EDDMapS goal is to maximize the effectiveness and accessibility of the immense numbers of invasive species observations recorded each year. As of August 2018, EDDMapS has over 4.4 million records.
