HAB Data Overview
Nevada's harmful algal bloom data is comprised of algae samples collected from public water bodies by trained state staff following the Strategic Response Plan (SRP) and Standard Operating Procedures (SOP). NDEP and analytical laboriatories analyze algae samples to make health advisory determinations. NDEP releases a Weekly HAB Update with the most recent data and health advisories. Please subscribe to the Nevada HABs Listserv to receive weekly HAB updates.
