Nutrient and Sediment Working Group

WQMA Nutrient and Sediment Reduction Working Group's Video:  "A Methodology for Evaluating Nutrient Reduction Practices"

The WQMA Nutrient and Sediment Reduction Working Group created a video that is a guide to a methodology for use in evaluating alternative techniques for reducing nutrient loading of waterbodies and selecting those that have the potential to be the most effective.   To view this video,  click here.

The Cayuga County WQMA has been discussing Code 590 at meetings in March and April. The code is available here.

WQMA Nutrient and Sediment Reduction Working Group Priorities for 2014:  


  1. Encourage municipalities to adopt local ordinances to minimize erosion and storm water impacts.
    • The Cayuga County Department of Planning and Economic Development (Planning) will work with Towns adjacent to Owasco Lake to encourage adoption of ordinances similar to Owasco’s Erosion and Sediment Control Plan for Small Homesite Construction ordinance.
    • Planning will conduct training to selected towns regarding incorporating steep slope protections into their development review process.
    • Planning will investigate the adoption of storm water regulations within the County and explore viable catch basin maintenance programs that could be implemented at the local level during subdivision and other development review procedures.
  2. Create additional educational materials including a user’s guide to assist in the use of the sediment and nutrient reduction practice evaluation methodology created by the Working Group.
    • A sub-group of the Working Group will develop the user’s guide in early 2014.
    • Additional materials supporting the user’s guide will be developed as needs become apparent.
  3. Specify sub-basins in which to focus sediment and nutrient reduction activities based on the priority waterbodies list and the Working Group’s map of areas having the highest relative potential for phosphorus loading based on their land cover characteristics.
    • Information in the report previously submitted by the Working Group will be supplemented by additional local knowledge to identify the specific sub-basins of primary interest in March 2014.
  4. Review the priorities of the other working groups’ and identify the ones that are the most closely related and synergistic.
    • The Working Group has already met to evaluate the other Working Groups’ priorities and has preliminarily identified five of them as the most synergistic. The Group will finalize the list following additional discussion and review of any updates or revisions offered by the other Working Groups in early 2014.
  5. Identify sediment and nutrient reduction strategies that also address priorities of the other working groups; recommend three to five strategies in several geographical areas.
    • The Working Group will generally apply its methodology to evaluate strategies that address multiple priorities in priority sub-basins.
    • The Working Group is especially interested in evaluating promising strategies for implementation in sub-basins where interest in sediment and nutrient reduction has already been demonstrated. (For example, cover crops in the Dutch Hollow sub-basin).
