Suisun Marsh Monitoring Project

Developing, implementing, and assessing the effectiveness of various Best Management Practices to address low dissolved oxygen and Methylmercury generation in Suisun Marsh.

Project At a Glance

Suisun Marsh, located northeast of San Pablo Bay, is approximately 116,000 acres, making it one of the largest contiguous wetlands in the entire state. It has been listed as impaired for dissolved oxygen/organic enrichment, mercury, nutrients, and salinity. It receives flows from upland watersheds, the Sacramento Delta, and much of it is subject to regular tidal action. Suisun Marsh also receives effluent from the Fairfield-Suisun Wastewater Treatment Plant, which treats to advanced secondary standards. 

This project is primarily funded by the US Environmental Protection Agency and the goals of the project are to:

  1. Identify constraints, opportunities and recommendations for managed wetlands BMPs in Suisun Marsh that could improve water quality relative to low dissolved oxygen and methylmercury generation
  2. Build knowledge within the managed wetland landowner community, and
  3. Develop working relationships amongst and across stakeholders to support attaining long‐term TMDL objectives.
