Harmful Algal Bloom Monitoring
Often visit lakes or reservoirs?
Enjoy using a microscope or interested to give it a try?
We need your help monitoring Utah for the presence of harmful algae!
Harmful algal (actually cyanobacteria) is naturally occurring in reservoirs, lakes and ponds, but with the increase in nutrients, low levels and warmer water, blooms are occurring more frequently around Utah and the world. These blooms are made up of billions of cyanobacteria: primitive nitrogen-fixing photosynthetic bacteria that thrive in warm, phosphorus rich waters.
While harmless in small concentrations, blooms sometimes produce toxins that can be deadly for humans, pets and livestock.

Participate in statewide monitoring with UWW and NOAA to help identify the occurrence of these blooms. See resources below.

Scope and Field Photos
If you find a potential bloom:
- For immediate concerns, contact the DEQ Spill Line (801) 536-4123. Otherwise, use the bloomWatch and/or UWW Google Form to report findings. Both of these will notify either the DWQ or UWW for follow-up.
- Use the NOAA database if you are regularly monitoring. Note: Report findings here even if you do not find any cyanobacteria.
Use this app to report a visual bloom in the field. App available on Android or iOS. By tagging Utah, a notification is sent to the Division of Water Quality. You may add photos and location of the bloom.
Use this form to submit photos and information of field and/or microscope data to the Utah Water Watch. We forward this information to the Division of Water Quality and local health departments. You may be asked to collect an additional sample for toxin tests.
(Note - you will need to be signed into a Google account to submit using this form).
Use this link to report microscope data to the NOAA phytoplankton Monitoring Network. Any positive hits of cyanobacteria, send photos to firstname.lastname@example.org for verification.
Utah volunteers use a similar login - if you are interested in participating, contact UWW at email@example.com or 435-797-2580.

Algal blooms may contain toxin-producing cyanobacteria. The following tips will help keep you safe. Be sure to bring gloves, safety/sun glasses, clean water and soap if none is available on site. Samplers should:
- Wear elbow/shoulder length gloves,
- Wear eye protection (such as sunglasses or goggles), and waders/boots during sampling.
- Do not ingest water or allow the water to come into contact with exposed skin.
- Avoid inhaling spray caused by boats, wind or other water surface disturbances. If these conditions are present, wear a mask to avoid inhalation of water spray.
- Hands should be washed thoroughly after sampling before eating or drinking with clean water (not lake water).
- Waders/boots should be rinsed of algal material using clean water (not lake water) before storage.
