| Abstract | The March 2013 Iowa Nutrient Reduction Strategy emphasizes implementation of technology-based nutrient controls and practices in the near-term, while retaining as a long-term goal the development of appropriate nutrient criteria. In 2010 the Iowa Department of Natural Resources (IDNR), with the assistance of a technical advisory committee, initiated a new project to build a technical foundation for stream nutrient criteria. This report presents results from an analysis of Iowa-specific nutrient data and a review of scientific literature and other relevant technical information. As an outgrowth of this work, nutrient enrichment criteria recommendations have been prepared for B(WW-1) and B(WW-2) wadeable, warmwater streams and B(CW1) coldwater (trout) streams. Current data are not adequate to formulate criteria recommendations for B(CW2) coldwater spring runs, B(WW-2) and B(WW-3) marginally perennial, headwater creeks of watershed area less than ten square miles, and large wadeable/nonwadeable rivers of watershed area greater than 700 square miles. IDNR continues to gather and analyze nutrient and biological-response monitoring data needed to develop nutrient criteria recommendations for all stream classifications. Going forward, a strong commitment to nutrient-related monitoring, data analysis, and reporting will be necessary to support development and implementation of nutrient criteria and the objectives of the state nutrient reduction strategy. |
