ATMOSPHERIC AND WATER QUALITY CORRELATES TO CYANOBACTERIAL DENSITY IN A SOUTHERN NEW JERSEY RESERVOIR

Cyanobacterial Harmful Algal Blooms (cHABs) are increasing in frequency and severity because of anthropogenic activities and climate change. When cHABs occur, they can alter ecosystem function and release toxins that are dangerous to humans, pets, and livestock. We studied Elmer Lake, a shallow polymictic impoundment on Muddy Run in southern New Jersey during the summer of 2019, during which time a cHAB occurred. A variety of water quality variables were significantly correlated with cyanobacterial density at both the dam and the headwaters of the reservoir. Significant correlations with atmospheric variables were observed at the headwater site, but not the site near the dam. These results suggest that bloom dynamics are different across locations within Elmer Lake despite its small size, shallow depth, and low shoreline development index. Future investigations of the relationship between atmospheric variables, water quality, and cyanobacterial density across lakes within the same watershed is critical for a comprehensive understanding of cHAB dynamics.
