DEQ and the Idaho Department of Health and Welfare (DHW) each play a role in identifying, responding to, and monitoring cyanobacteria harmful algal blooms (HABs).
The health advisory map is available on DHW’s Recreational Water Health Advisories web page.
Our staff is responsible for sampling Idaho water bodies and analyzing water quality data. We provide the sample results to DHW and the public health district in the area where a citizen reported the HAB, and they decide if it warrants a health advisory.
Water Quality Test Results
As water quality sample results become available, you will see them in the table below.
