More recent changes in precipitation patterns combined with urban expansion and wetland losses have resulted in an increase in the frequency and intensity of flooding in parts of Minnesota with extensive and costly damage to the state's infrastructure and ecosytems. We are examining historic climate records and developing a database of key climatic measures and their variability in a current LCCMR project “Impacts on Minnesota's aquatic resources from climate change.” To assess the consequences of past climate trends on aquatic resources we are analyzing hydrologic, water quality, and fish community responses. We propose to expand that study to develop prediction for future climate specific to Minnesota, and then quantify the potential economic impact of climate-induced changes in precipitation and hydrology on the water resource infrastructure, including storm sewers, bridges, water treatment facilities, and shoreline development. The current biological analyses will be expanded beyond fish to invertebrates (e.g., mosquitos) and projections of future biotic responses from hydrologic and water quality models will be developed. Lastly, to assist the state's natural resource managers and regulators, we will identify potential hydrologic and aquatic indicators and propose monitoring methods that can be implemented in Minnesota. An advisory committee will help define the initial questions to be answered and review productsenClimate changeMinnesotaWater quality monitoringEnvironmental impactNatural Resources Research InstituteUniversity of Minnesota DuluthTechnical Report
