Colorado Instream Flow Program ExitIn Colorado’s semi-arid environment, water is scarce with many competing demands placed on it by an ever-increasing population. The Colorado Water Conservation Board is responsible for the appropriation, acquisition, protection and monitoring of instream flow and natural lake level water rights to preserve and improve the natural environment to a reasonable degree.

Colorado Watershed Flow Evaluation Tool ExitThis project demonstrates the use of flexible approaches to develop flow-ecology curves based on studies reported in the literature and demonstrates the use of flow-ecology curves to inform basin-scale water-resource planning.

Wyoming Wetland Complex Inventory and Assessment (PDF) (9 pp, 2.68 MB) ExitThis is a landscape-scale geospatial assessment of wetlands in Wyoming for identifying and mapping 'wetland complexes' and quantifying the relative importance of these complexes in terms of biodiversity, recreational potential, agricultural influence, current condition and vulnerability to future environmental changes. It is based on an overlay analysis of 16 different data layers.
