Changes to water resources are critical to all sectors of the economy. Climate change will affect the timing and quantity of water available in the environment as well as have an adverse effect on the quality of that water. Floods, droughts, and changing patterns of water scarcity—when water is not available in sufficient enough quantities or of a suitable quality at the right time to fulfill demand—are all critical factors when considering how and where Indiana will be able to economically develop in the future. Management of water resources will become even more important as different sectors try to minimize the risk of water scarcity in the face of increasing climate variability. This paper focuses on observed changes to Indiana’s water resources and how the availability and quality of those resources are likely to change in the face of future climate. Generally, Indiana is becoming wetter but with the projected increase coming primarily in the winter and spring. Summer water use will increase the likelihood of water shortages and the need for improved water management. In particular, Indiana may benefit from investment in methods to increase short-term storage of water—retaining more of the overabundance from winter and spring to relieve summer shortages.

水资源的变化对经济的各个部门都至关重要。气候变化将影响环境中可用水的时间和数量，并对水质产生不利影响。洪水，干旱和水资源短缺的变化模式（当在适当的时候没有足够数量的水或适当质量的水来满足需求时）都是考虑印第安纳州如何以及在何处能够经济发展的关键因素。未来。面对越来越多的气候变化，随着不同部门试图将水资源短缺的风险降到最低，水资源的管理将变得更加重要。本文着重于观察到的印第安纳州水资源变化，以及面对未来气候变化，这些资源的可利用性和质量将如何变化。总体而言，印第安纳州变得越来越湿，但是预计的增加主要是在冬季和春季。夏季用水将增加缺水的可能性，并需要改善水管理。特别是，印第安纳州可能会受益于增加短期储水量的方法的投资-保留冬季和春季更多的过剩资源，以缓解夏季的短缺。
