IllinoisNutrient LossReduction Strategy
The Illinois Nutrient Loss Reduction Strategy, NLRS, is a statewide, collaborative effort working to reduce the amount of nutrients, particularly nitrogen and phosphorus, entering Illinois waterways.
This website details the efforts and investments made by NLRS partners and stakeholders across the state to reduce nutrient loss from the agricultural, point source, and urban stormwater sectors.

TOPIC AREAS: WATER QUALITY & NUTRIENT SOURCES




Our work centers on four critical areas affecting Illinois waterways. The Illinois NLRS tracks and shares updates on:
- Water Quality - Nutrient loads and trends in Illinois rivers.
- Agricultural & Non-Point Sources - Implemented conservation practices and programs that support nutrient loss reduction from agricultural non-point sources.
- Point Sources - Nutrient reduction efforts from municipal and industrial wastewater treatment facilities.
- Urban Stormwater - Green infrastructure practices that address nutrient loss from urban landscapes.
INTERACTIVE DATA MAPS




Explore spatial data and track nutrient reduction efforts using NLRS interactive maps.
These maps visualize water quality, agricultural non-point sources, point source, and urban stormwater trends across Illinois.
Our goal is to provide clear, actionable data to support informed decisions and collaborative strategies for improving Illinois waterways.
