This dataset was developed in partnership with the Tennessee Department of Environmental Conservation to determine the susceptibility of selected Tennessee reservoirs to eutrophication and potential harmful algal blooms. A R script, based on recursive partitioning and the model-based boosting routine, was used to generate regression trees that grouped Tennessee reservoirs into five endpoints along individual low-to-high gradients of Secchi depth and chlorophyll a concentrations (Green, et al, 2021; Heal and Green, 2021). Input data for these reservoirs were obtained from SPAtially Referenced Regression On Watershed (SPARROW) attributes models that estimate total phosphorus and total nitrogen loads in Tennessee water...

Lake Texoma is home to several isolated coves walled off by sedimentation as a result of reservoir aging. The habitat fragments are relatively new features on the landscape, isolated from the reservoir and taking diverse forms. These fragments have been formed on the arms of two physicochemically distinct rivers entering Lake Texoma (Red and Washita). Fragmented coves are located within the river-reservoir interface, a highly productive and ecologically important transitional zone. We examined the structure of young-of-the-year (YOY) fish assemblages utilizing these habitats and investigated the influence of environmental factors on taxonomic and guild composition. Sampling was carried out from March through August...

We propose to empirically characterize hydrology/fish-production relationships for different ecological groups of fishes living in the Red River and associated reservoir habitats by: 1. Correlating historic hydrologic data with catch curve residuals, and 2. Annual growth rate estimates of fish collected from the Red River and associated reservoirs. The catch curve residual approach for indexing year class strength has been validated and successfully used to quantify the relationship between reservoir hydrology and YOY recruitment for white crappie and largemouth. The essence of the approach is as follows. Catch curves (a correlation between the natural log of fish abundance and age) are used to measure total instantaneous...
