Cyanobacteria Plan Advisory Committee

Preparing a statewide cyanobacteria strategy for New Hampshire.

The Cyanobacteria Plan Advisory Committee was created in response to legislation in 2022 mandating NHDES to prepare a statewide cyanobacteria strategy by November 1, 2023.

HB 1066 calls for NHDES to "prepare a plan to prevent the increase of, and eventually control, cyanobacterial blooms in New Hampshire's lakes and other waters. Such plan shall be supported by scientific data and shall include measurable milestones. The commissioner shall determine the organizational structure, foci, personnel, and resources needed to execute the plan. The commissioner shall also coordinate with appropriate stakeholders as may be required to execute the plan. [...] The plan shall be submitted in writing to the governor, the speaker of the house of representatives, and the president of the senate no later than November 1, 2023."

New Hampshire’s Cyanobacteria Plan

House bill 1066, passed in the 2022 legislative session, directed NHDES to develop a plan to prevent the increase of, and eventually control, cyanobacteria blooms in New Hampshire’s waterbodies. The plan included input from a 17-member advisory committee and specifies the actions needed to achieve the legislative directive.
