California Cyanobacteria and Harmful Algal Bloom (CCHAB) Network
- SWAMP released a Statewide Freshwater Harmful Algal Bloom Assessment and Support Strategy that outlines actions and infrastructure being developed to support local response to HAB events.
- To work towards the development and maintenance of a comprehensive, coordinated program to identify and address the causes and impacts of cyanobacteria and harmful algal blooms (HABs) in California.
Background and Description
The CCHAB Network, formerly the Statewide Blue-Green Algae Working Group, was established in 2006 in response to record-setting toxin producing blooms in the Klamath River reservoirs. Since its establishment, the CCHAB Network has developed guidance for responding to HABs, including action levels for cyanotoxins; held trainings on HAB identification and sampling; and funded a number of grant projects. These efforts demonstrated a need for the development of a long-term vision and strategic plan for identifying and managing HABs in California. Four key goals were identified – prioritization of management questions, synthesis of existing data, identification of data gaps, and the development of communication tools.
Objectives of the CCHAB Network?
Develop a unified multi-entity program to identify and address HABs in California's freshwater ecosystems.
Promote improvements in, and coordination of monitoring assessment, reporting, and management of HABs in California.
Develop collaborative relationships among entities (e.g. federal, tribal, state, and local agencies, academic researchers, end-users and stakeholders) responsible for addressing HAB concerns and impacts on beneficial uses.
Coordinate with the California Harmful Algal Bloom Monitoring and Alert Program (CalHABMAP).
Make efficient use of federal, tribal, state, regional, and academic resources to address cyanobacteria and HAB concerns by sharing information to avoid duplicative efforts; promoting research, monitoring, and assessment; identifying technical and policy gaps; and communicating HAB concerns to the public.
Work collaboratively toward public awareness of the risks associated with HABs to people, pets, livestock and wildlife
CCHAB's Relation to the Monitoring Council?
The CCHAB Network is a workgroup of the California Water Quality Monitoring Council. The Monitoring Council establishes common policies and guidelines for the workgroups and the programs they represent, acts as a clearinghouse for standards, guidelines, and collaboration; resolves key issues that affect multiple workgroups; provides support for workgroup actions, and improves visibility of workgroup efforts. The CCHAB Network will keep the Monitoring Council apprised of progress towards workgroup goals and will raise issues to the Monitoring Council that cannot be resolved within the workgroup or that may affect multiple workgroups of the Monitoring Council.
CyanoHAB Guidance for Recreational Water Uses
When a cyanoHAB is occurring, it is critical that there is understanding of the cyanobacteria and cyanotoxins present and communication of the risk to protect public health. Currently, there are no federal or state standards for cyanotoxins in drinking water and recreational waters. Participating agencies - State Water Board, OEHHA, and CDPH - have developed and are further refining suggested guidelines for addressing health concerns for cyanotoxins in recreation waters. The Department of Public Health, county health departments, and water body managers are encouraged to use this guidance for posting of water bodies when cyanoHABs pose a health threat.

- SIGNS: The PowerPoint files allow deletion of individual icon/text message components that may not be appropriate for a specific water body. However, text with each component cannot be changed. Components may be moved to allow more space for local agency contact information (text box at the bottom of each sign). Signs are available in both English and Spanish. (version 8/5/2016)

California Cyanobacteria and Harmful Algal Bloom Network is made up of a diverse group of stakeholders that address, research, manage, and/or regulate cyanoHAB concerns in California. The CCHAB Network is composed of federal agencies, state agencies, tribal governments, local agencies, academics and researchers, and other stakeholders.
