Intensities of agricultural nutrients (48 states)

Map of intensities of agricultural nutrients (48 states)

Detailed Description

Estimates from USGS models enable tracking of nutrients and their sources from local streams to reservoirs used for drinking water and ultimately to our nation's estuaries and Great Lakes. Understanding which sources and areas are contributing the highest amounts of nutrients can inform nutrient reduction strategies. Map from Preston, et al, 2011.
