Although water quality protection is a priority for water agencies in lake-rich areas like the Upper Midwest, budgets restrict the number of lakes monitored. As a result, agencies cannot identify and manage all water resource problems.

At the University of Minnesota's Water Resources Center and Remote Sensing Laboratory, analysts are developing a new monitoring approach. With images captured from earth-observing satellites, they're estimating lake and stream water clarity and mapping aquatic vegetation at city, state and regional scales.
