Delta Cyanobacteria Harmful Algal Blooms

Monitoring Strategy

Cyanobacteria harmful algal blooms (CHABs) have been a water quality issue in the Sacramento-San Joaquin Delta for decades, and many studies have been conducted to better understand their impacts on the ecosystem and public health. However, no monitoring framework for CHABs exists in the Delta.

The Delta CHABs Monitoring Strategy was developed to address the needs of the science community and establish a pathway for creating a community-informed monitoring program that addresses CHABs in the Delta. The strategy provides an approach to advancing the management of Delta CHABs by coordinating the collection of priority data, promoting data-sharing, and identifying feasible mitigation techniques for reducing HAB prevalence. Authored by Ellen Preece (Department of Water Resources), Mine Berg (Environmental Science Associates), Tricia Lee (Delta Science Program), Karen Odkins (Department of Fish and Wildlife), and Jenna Rinde (Department of Fish and Wildlife), with extensive input from public meetings and review periods, this document is intended to support collaborating agencies, scientists, and others interested in helping to manage this important issue in the Delta.



The strategy will be implemented through an Interagency Ecological Program Project Work Team, which you can learn more about below.
