Project Number: 5030-13000-012-021-I
Project Type: Interagency Reimbursable Agreement
Start Date: Sep 1, 2025
End Date: Sep 30, 2029
Objective:
Identify regionally-relevant conservation approaches that may mitigate stream sediment legacy phosphorus sources or that will be effective in conjunction with field and edge-of-field conservation practices identified in an earlier phase of this Legacy Phosphorus project. Results will help link field, edge-of-field, and downstream practices to develop comprehensive watershed conservation strategies. Specific objective is to help collect and ship stream reach sediment samples from the Upper Mississippi River Basin sampling locations that are found in proximity to Ames, Iowa.
Approach:
1. Identify 10-20 individual stream reaches with the South Fork CEAP watershed site.
2. Conduct stream legacy phosphorus sampling activities at 10-20 stream reaches.
3. Develop datasets that describe relationships between watershed conditions, stream reach characteristics, and labile P and buffering capacity within stream sediments.
