The Vollenweider (1976) hydraulic- residence form and the equivalent formulation of Larsen and Mercier (1976) are available as alternatives. Predicts in-lake total phosphorus, total nitrogen, chlorophyll-a, and Secchi depth from tributary nutrient and hydraulic loading inputs, and computes Carlson (1977) Trophic State Indices. Optional Oklahoma-specific chlorophyll and Secchi regression coefficients are provided, calibrated from publicly available state lake monitoring data. Supports single-segment and multi-segment reservoir configurations and load-reduction scenario analysis. Designed to complement watershed loading models such as the Soil and Water Assessment Tool ('SWAT'; ) and the U.S. EPA Hydrologic and Water Quality System ('HAWQS'; ) in a two-model nutrient management workflow. authors: - family-names: Henderson given-names: Jordon email: jordon.henderson@owrb.ok.gov repository: https://cran.r-universe.dev repository-code: https://github.com/0011235813/Oklahoma-BATHTUB commit: 4004f46444947c9a544a02a032ebff0ac20545d2 url: https://0011235813.github.io/Oklahoma-BATHTUB/ date-released: '2026-05-29' contact: - family-names: Henderson given-names: Jordon email: jordon.henderson@owrb.ok.gov
