Water Quality Analysis of the Thorgren Naturalized Detention Basin

Abstract

This paper offers a study demonstrating an integrated stormwater best management practice for nutrient removal, runoff temperature reduction, suspended solids removal, enhanced hydraulic performance and runoff storage, and improved biological integrity. The study includes data collected from the Thorgren Detention Basin in Valparaiso, Indiana, originally designed as a dry-bottom detention basin and comparison data collected from the redesigned naturalized, wet-bottom, basin. Additional information is presented about the construction, finance, operation, and performance monitoring of the basin. We found a significant stormwater quality improvement due to the implementation of the detention basin naturalization effort.
