PRECISION CONSERVATION HAS THE POTENTIAL TO DRAMATICALLY REDUCE NONPOINT SOURCE NUTRIENT POLLUTION. BY COMBINING HIGH-SPATIAL RESOLUTION GEOSPATIAL DATA AND HIGH-FREQUENCY INSTREAM NUTRIENT DATA, WE WILL BE ABLE TO DEVELOP UNDERSTANDING OF HOT SPOTS AND HOT MOMENTS OF NUTRIENT POLLUTION. DATA WILL INCLUDE HIGH-FREQUENCY TIME SERIES OF NITRATE CONCENTRATION, DISCHARGE, DISSOLVED OXYGEN, ELECTRICAL CONDUCTIVITY, AND PAR AT STREAM REACH (UPSTREAM AND DOWNSTREAM OF CSA), SUBCATCHMENT, AND SUBWATERSHED SCALES. SPATIAL DATA WILL INCLUDE HIGH-RESOLUTION (1M2) DATA OF HOTSPOTS AND POTENTIAL BMP LOCATIONS TO MITIGATE POLLUTION. A MORE SYSTEMATIC UNDERSTANDING OF HOW MULTIPLE HYDROLOGICAL AND BIOGEOCHEMICAL PROCESSES CONTROL C-Q PATTERNS ACROSS MULTIPLE SPATIAL AND TEMPORAL SCALES IS REQUIRED FOR EFFECTIVE WATERSHED MANAGEMENT STRATEGIES.
