Toxic cyanobacterial harmful algal blooms (HABs) have increase in New Jersey ponds, lakes, and reservoirs since 2018. Community water monitoring groups are spread out across the state and can help to quantify the extent of these algal growths through visual lake assessments and phycocyanin measurements.

Anyone can submit visual lake data using the link above! Just select your favorite pond, lake, or reservoir and visit the same site every 1-2 weeks to watch and share how lake conditions change from May to September. 

With a bulk equipment loan from the EPA Region 2 Citizen Science Program, New Jersey has a few dozen fluorometers available for loan to community water monitoring groups in 2021. Groups can request a fluorometer to measure phycocyanin levels along with a visual assessment to confirm the presence of suspected HABs and to prioritize additional monitoring and action.
