Summary

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.

Purpose

The goal of this proposed project is to assess the potential for changes in water quality and trophic status of Lake Mead due to increased internal nutrient recycling that may result from warmer water temperatures and lower dissolved oxygen concentrations which are induced by climate change. Specifically this project will address: 1. The potential for warmer climatic conditions to lead to increased internal nutrient recycling due to lower dissolved oxygen concentrations in Lake Mead. 2. The effect of increased internal nutrient recycling on general water quality and trophic status of Lake Mead. 3. The effect of increased internal nutrient recycling on the potential for large algal blooms, which may reduce water transparency and lead to a general degradation in recreational uses in the lake. 4. The potential for increased internal nutrient recycling and productivity to lead to further decreases in dissolved oxygen concentrations and additional nutrient release through “feed-back” mechanisms.
