The Vollenweider (1976) hydraulic- residence form and\nthe equivalent formulation of Larsen and Mercier (1976) are\navailable as alternatives. Predicts in-lake total phosphorus,\ntotal nitrogen, chlorophyll-a, and Secchi depth from tributary\nnutrient and hydraulic loading inputs, and computes Carlson\n(1977) Trophic State Indices.\nOptional Oklahoma-specific chlorophyll and Secchi regression\ncoefficients are provided, calibrated from publicly available\nstate lake monitoring data. Supports single-segment and\nmulti-segment reservoir configurations and load-reduction\nscenario analysis. Designed to complement watershed loading\nmodels such as the Soil and Water Assessment Tool ('SWAT';\n) and the U.S. EPA Hydrologic and Water\nQuality System ('HAWQS'; ) in a\ntwo-model nutrient
