Interactive Data Dashboards
The process of reporting Iowa Nutrient Reduction Strategy efforts transitioned in 2021 to a revised approach by publishing data and findings in a set of web-based dashboards. This revised reporting structure aims to increase the timeliness, frequency, and transparency of updates on Iowa Nutrient Reduction Strategy efforts and nutrient loss in Iowa. Access topic-specific dashboards below.
This dashboard presents data and findings on the use of land use and in-field nutrient reduction practices in Iowa agriculture. These practices have the potential to reduce nitrogen and phosphorus loss from agricultural fields to surface water bodies.
This dashboard presents data and findings on the use of edge-of-field and structural erosion control practices in Iowa agriculture. These practices have the potential to reduce nitrogen and phosphorus loss from agricultural fields to surface water bodies.
This dashboard displays the status of permits issued by the Iowa Department of Natural Resources to facilities identified in the Iowa Nutrient Reduction Strategy. Facilities include major publicly owned treatment works, minor domestic facilities, and industrial facilities.
Tracking Funding and Resources
This dashboard will present data and findings on the extent of funding and resources dedicated to Iowa nutrient reduction efforts and water quality improvement.
Tracking the Human Dimension
This dashboard will provide data and findings on farmer survey data, outreach, and education.
Tracking Water Quality and Nutrient Export
This dashboard will provide data and findings on water quality monitoring. It will also provide links to extensive resources on more detailed water quality monitoring data.
The Iowa Nutrient Reduction Strategy is a science- and technology-based approach to assess and reduce nutrients delivered to Iowa waterways and the Gulf of Mexico. The strategy outlines opportunities for reducing nutrients in surface water from both point sources, such as municipal wastewater treatment plants and industrial facilities, and nonpoint sources, including agricultural operations and urban areas, in a scientific, reasonable, and cost-effective manner. The Iowa Nutrient Reduction Strategy was developed in response to recommendations provided by the United States Environmental Protection Agency (EPA) in its March 16, 2011, memo, “Working in Partnership with States to Address Phosphorus and Nitrogen Pollution through Use of a Framework for State Nutrient Reduction.” Ongoing action for nutrient load reductions is further supported by the recent EPA recommendations, “Renewed Call to Action to Reduce Nutrient Pollution and Support for Incremental Actions to Protect Water Quality and Public Health,” released September 22, 2016.
