Science & Restoration

Harpeth Conservancy's Science & Restoration program plans and implements projects that protect and improve water quality and ecosystem health in Tennessee rivers. These projects can be divided into three categories:
(1) River Science Research, (2) River Restoration, and (3) TN Water Watch.


We carry out a large variety of science and restoration projects every year, with assistance from experts, dedicated volunteers, governmental agencies, corporate partners, civic groups, and other watershed stakeholders. Our science research seeks to strategically study and monitor our rivers to better understand their overall health as well as current and potential threats such as pollution and degradation. Our restoration efforts, ranging from river cleanups to streambank stabilization, ultimately reduce pollution to the river, enhance habitat, and protect aquatic wildlife. Our TN Water Watch is a first-of-its-kind river advisory tool. Using years of our own water sampling data AND real-time environmental data (weather, river flow, precipitation, etc.), we can combine this information to PREDICT levels of E. coli at various river access points.
