KDHE has historically responded to HAB issues in Kansas lakes. Due to the increase in notable HAB occurrences, the agency began formalizing a complaint-based response program in 2010. Once a complaint has been validated through field observations, a sample is collected. The sample is examined for the presence of blue-green algae and tested for toxins.
A standard protocol is followed to determine whether public advisories should be issued and to decide the next course of action for monitoring the affected water body. The current HAB season extends from April to October when lakes are most likely to be affected by HABs and members of the public are most likely to recreate in waterbodies.
If a HAB is confirmed in a public water body, KDHE issues advisories works with lake managers to inform the public, and continues to monitor the waterbody until the bloom has subsided.
The KDHE protocols can be found in the "Harmful Algal Bloom KDHE Agency Response Plan."
