Flow Exceedance Maps for Michigan based on Real Time & Historical Data
Track: Water Resources
Authors: Marlio Lesmez, Chad Fizzell

The 2012 drought created a need to know the status of Michigan’s watersheds. Combining GIS and USGS stream and exceedance flow data made that possible. A map application compares instantaneous flows with monthly exceedance to determine the status of the watersheds. The application produces maps in PDF format and can also be used to provide spatial exceedance characteristics of the watershed from historical records. The results can be compared with rainfall data to investigate climate trends.
