The Secchi Dip-In is a demonstration of the potential of volunteer monitors to gather environmentally important information on our lakes, rivers, and estuaries. Volunteers have been submitting information during the annual Dip-In since 1994. In the months ahead, volunteers will be able to include additional water chemistry and in situ information as part of enhancements to the Dip-In database. To access public data, use the username 'public' and leave the password blank. For other support, visit the NALMS Secchi Dip-In site or send an email to secchidipin@nalms.org
