Public Information Session Scheduled For July 8, Regarding Brown's Mill Dam Removal In Rutherford County

Friday, June 20, 2014

The Tennessee Wildlife Resources Agency will be hosting a public information session in regard to the Browns Mill Dam removal and river access on the East Fork of the Stones River in Rutherford County.

The session will be held on Tuesday, July 8, at the Lascassas Fire Hall. Anyone interested in this project may come anytime between 6:30 and 8 p.m. TWRA and Griggs and Maloney Engineering & Environmental Consulting staff will be available to answer questions on the project.

Pursuant to Chapter 1200-4-7 of the Department’s rules, the proposed activity described below
has been submitted for approval under an Aquatic Resource Alteration Permit and §401 Water
Quality Certification.

This notice is intended to inform interested parties of this permit
application and to ask for comments and information necessary to determine possible impacts to
water quality. No decision has been made whether to issue or deny this application.
APPLICANT: City of Murfreesboro
Jim Crumley, Assistant City Manager
111 West Vine Street
Murfreesboro, TN 37130
615-893-5210
LOCATION: Brown’s Mill Dam, East Fork Stones River near Lascassas in Rutherford
County. 35.901944, -86.28111
PROJECT DESCRIPTION / PURPOSE: The applicant is requesting a §401 water quality
certification that would authorize removal of remnants of Brown's Mill Dam, construct an
equipment access point to the river and install a j-hook deflection structure to protect the access
point. The stated project goal is to provide a river access and restore the fluvial geomorphology
and biological connectivity of the East Fork Stone's River at that location.
At the project site, the river ranges from 75 to 125 feet wide, consists of riffle/pool sequences
below the dam, and is dominated by cobble, boulder, and bedrock substrate, Water depth at 100
cfs flow ranges from 6 inches in the riffles to -5 feet in the pool areas. The substrate above the
dam is markedly aggraded, consisting of gravel and small cobble with the flow spread evenly
across the channel. Water depth in the impounded section remains constant at about 2 feet deep
at the about 100 cfs. The riparian zone is well developed and is dominated by box elder,
sycamore, black willow, and silver maple,
The remnant Brown's Mill Dam headwall and apron would be removed in phased sequence as
depicted in Figure 8 (attached). Starting at the far right bank (facing upstream), the dam headwall
and apron remnants would be removed by mechanized equipment, e.g. track hoe, hoe-ram,
pneumatic hammer, etc. Activities would be performed, to the greatest extent practicable, in the
dry by diverting water from the work site through installing temporary water bladder coffer dams
upstream from the work face and operating equipment atop temporary gravel pads constructed
from native stone riverine deposits that would be obtained in the immediate vicinity of the work
site.
All construction equipment would be operated from below the dam. Material removed would be
taken to an upland surface depression that is targeted for future vehicle parking and used as
structural fill. The demolition scenario previously described would be repeated at each section of
the dam as activities proceed across the ~ 75ft. span. The applicant estimates that approximately
40 cubic yards of concrete would be removed during this project. The aggraded material that has
deposited upstream of the dam, consisting largely of cobbles and large gravel, (See Figure 10)
would not be removed or altered in any fashion. Natural bed load redistribution would return this
stream segment to pre-impoundment conditions by the river's fluvial action. All work would be
performed during low flow conditions, as determined by instantaneous discharge monitoring
obtained from the USGS East Fork Stones River Gauging Station.
DETERMINATIONS: In accordance with the Tennessee’s water quality standards, the
division has determined that the proposed activity will not result in degradation.
