The average Secchi disk reading for 2023 was 6.7 meters, which falls into the moderate clarity range. The average total phosphorus reading was 7.5 ppb, which falls into the moderate range. The average deep water phosphorus
value is more than 10 ppb above average surface water phosphorus values, which indicates phosphorus recycling may be an issue. The chlorophyll-a average of 2.2 falls into the moderate range. Long-term trend analysis indicates chlorophyll-a concentrations in Adams Pond are stable, total phosphorus concentrations are stable, and clarity readings are stable. Gloeotrichia echenulata colonies were not observed in Adams Pond in 2023.
Adams Pond surface water chlorophyll (ppb), phosphorus (ppb), and Secchi depth (meters) data comparison. Colored areas represent the long-term range of values, from minimum to maximum. Area thickness indicates frequency of measurements at that value. Area thickness increases as more measurements are reported at that value. The vertical black line represents the long-term average value. The large red dot represents 2023’s average value. The small red dots represent individual readings taken in 2023.
Gloeotrichia echinulata (a type of cyanobacteria (blue-green algae) commonly found in low-nutrient waters) can be seen with the naked eye. Gloeo density is reported as a value ranging from 0 – 6, based on the number of Gloeo colonies seen through a Secchi scope. Higher values indicate more Gloeo colonies. Gloeotrichia echenulata colonies were not observed in Adams Pond in 2023.
