Look Out for Harmful Algal Blooms
The official beach monitoring season comes to an end after Labor Day weekend, but we do continue to receive and investigate reports of harmful algal blooms (HABs) throughout the fall. If you suspect a waterbody is experiencing a bloom, call or text the hotline at (603) 848-8094 or email HAB@des.nh.gov. Stay up-to-date on cyanobacteria advisories by checking our Beach Advisory Map.
