Southern Nevada Water Authority will add new modeling and analytical capabilities to tools developed as part of a previous WaterSMART Climate Analysis Tools Grant that assessed impacts of climate change on water quality and sediment transport in Lake Mead. Project results are intended to increase an understanding of how water quality characteristics and nutrient levels in Lake Mead may be affected by climate change.

Our approach will include sampling a wide range of habitats and environmental conditions throughout the middle and lower Pecos River basin, across an 18 month time-span to account for seasonal and phenological events. We will utilize a suite of univariate and multivariate statistical techniques to relate occurrence and density of golden alga to environmental factors and other co-occurring organisms. The proposed research will benefit managers of the Pecos River, of its associated reservoirs and unique habitats (sinkholes on the Bottomless Lakes State Park and Bitter Lakes National Wildlife Refuge), and of its resident aquatic biota by identifying specific water quality attributes that promote golden alga bloom development...
The Desert LCC will provide the 50% of the Federal component of funds, and the work designed will support the science objectives for the Desert LCC and its partners as well as provide needed improvements to the National Hydrography Dataset (NHD) in the Lower Colorado River Region, and beyond. Basic improvement of the NHD at the 1:24,000 scale will provide an important framework basis for the development of hydrologic models required to address effects of climate change. An accurate surface water map will support the following specific DLCC objectives and needs: Hydrologic and biological modeling Accurate determination of perennial and intermittent classification Impacts on flow due to storms (particularly in the...
