The Secchi Dip-In is an annual event involving water quality volunteer monitors nationwide. Equipped with their Secchi disks, volunteers have been gathering environmentally important information on 7,000 waterbodies — lakes, rivers, and estuaries — for more than 25 years. Although the Dip-In is held in July, volunteers are welcome to monitor water quality and submit data year-round!
