Droughts and earlier snowmelt runoff will increase water scarcity during the summer peak water demand period especially in regions with extensive irrigated agriculture, leading to economic losses and increased pressures on groundwater as a substitute for diminished surface water supplies  . Streams in North America are expected to continue to warm, with important ramifications for aquatic ecosystems , reducing habitat for salmon and trout species that are economically and culturally important . Warming and drying coupled with other stressors  pose a risk to ecosystem structure and function in lakes, streams and reservoirs across many parts of North America  . Warming increases in heavy rainfall and nutrient loading pose risks for water quality and HABs  .
