“The dataset includes raw water‑quality measurements and derived ecological indicators for lakes, ponds, and reservoirs in the Winooski River Basin. Variables include chlorophyll‑a, dissolved oxygen, Secchi depth, total nitrogen, and total phosphorus, along with Carlson Trophic State Index metrics, nutrient ratios, nutrient‑limitation categories, and risk quotients for nitrogen, phosphorus, and chlorophyll‑a. Each row corresponds to a single waterbody and includes geographic coordinates and waterbody classification. Derived variables were computed using the procedures outlined in the manuscript, while raw measurements remain unaltered.”
