Thoughts going forward…..

• Watershed nutrient budgets are needed, especially those with high livestock density

• INRC and INRS need to focus on using Watershed Approach to reach WQ objectives

• Evaluation/monitoring of WQI projects is needed, along with more demonstration watersheds with high level of adoption

• We need new practices

• We need strategic communication
