2016 Parameter Data: Total Phosphorus, River, Brook and Tributary Sites In fresh water bodies, phosphorus is the nutrient that has the most influence on plant growth. Just parts per billion (ppb) increases are needed to stimulate the growth of algae. Measurement of total phosphorus includes readily available dissolved phosphorus, as well as particulate phosphorus and organic forms of phosphorus such as that making up algae. Phosphorus readily binds to lake sediments, but can be released back into the water column if there is no oxygen in the bottom waters of the lake, as can occur when lakes stratify in the summer. That process, known as internal phosphorus recycling, can cause late summer or early fall algae blooms when lakes destratify, or become well mixed in the fall. For more information on phosphorus, lake aging and how you slow it, see our factsheet at http://cels.uri.edu/docslink/ww/water-quality-factsheets/Phosphorus.pdf. Watershed LOCATION MAY JUNE JULY AUG.
