Duck River, Tennessee

The Duck River is the most biologically diverse river in the United States and is also the source of drinking water for 250,000 people in Middle Tennessee. In recent years, Trutta has completed 155 miles of High Definition Stream Survey (HDSS). Completing this would have been impossible if not for the partnerships. We have partnered with a group of collaborators from various organizations (Duck River Agency, Tennessee Department of Environment and Conservation (TDEC), Columbia Power and Water Systems (CPWS), South Central Tennessee Development District (SCTDD), Tennessee State Parks, Stantec, O’Brien & Gere, and InfloDesign). These surveys collected a huge amount of valuable data to assist managers in making good decisions to achieve their goals, while keeping the Duck River healthy.

Flow Modeling

Our work began below Normandy Dam with TDEC. They were interested in cross-sections data for TMDL flow modeling at one-mile increments. The Cities of Lewisburg and Columbia each funded additional high-density cross-sections in their respective reservoirs for both drinking water and wastewater purposes.

Drinking Water

Since then, that data has been used by Columbia Power and Water to estimate current reservoir capacities for various water needs including drought planning. Engineering firms, such as O’Brien and Gere, Stantec, and InfloDesign have used the data for monitoring current drinking water intakes, as well as siting new drinking water intakes in collaboration with different municipalities and the Duck River Agency.

River Corridor Data

While collecting bathymetric data throughout the years, we also ran the HDSS system to collect longitudinal river corridor data. Every mile of river has StreamView video, depth data, and side scan sonar imagery that can be used for numerous different water resource management purposes.  MS4 stormwater permitting, streambank restoration prioritization, and habitat suitability modeling are just some of the ways that this data could be used today.  With the surveys already completed, this data can be made available to you at a reduced cost.

Other Uses for HDSS Data

Trutta has also been in discussions with Tennessee Wildlife Resource Agency (TWRA) to help determine habitat for endangered mussel species, with the National Resources Conservation Service (NRCS) about suitable locations for streambank plantings, and Tennessee State Parks about using the video for information and education.
