Building Science Assessments for State-Level Nutrient Reduction Strategies was a multi-day workshop -- held November 13-15, 2012 in Davenport, Iowa -- at which attendees and speakers worked to a) present the process and results of the science assessment work being done in Iowa on nutrient reduction, b) provide a workshop environment for state and regional teams in the Mississippi River Basin to collaborate on developing or advancing the process for their state science assessments, c) offer presentations and posters on additional science resources available to state teams for developing their assessments, and d) discuss current information on additional science questions.
