Why Duck River

The Phase I Study prepared by Lockwood Green and the U.S. Army Corps of Engineers determined that future demands would require a new water source to provide a minimum of 18 mgd during drought conditions. Twenty alternatives were identified and developed to a point of cost and amount of water it could produce. The final recommendation made by the U.S. Army Corps of Engineers was to construct a dam on Duck River and create a new reservoir. This option meets all of the requirements of the original study and remains the best option as further environmental and other research was conducted. The Corp of Engineers even remarked that the Duck River created one of the most natural dam sites they had ever seen.

Some of the reasons Duck River was the preferred alternative:

  • Cost (based on environmental consequences, cost and supply potential).
  • Proximity to current treatment plant.
  • Would supply 32 mgd which could be used as a primary water source, supplemental source, or emergency source and would meet the water needs of the Region for at least 75 years.
  • No threatened or endangered species.
  • Minimal wetland loss of 1.32 acres.
  • The Buffer Zone (100 feet) around the reservoir will be managed for old growth timber and wildlife.
  • Creation of the impoundment will result in the development of a lake fishery.

The Plan

A 135-foot high dam would be constructed on the Duck River and would be approximately 2,000 feet in length. The dam would be located approximately 1,000 feet north of Highway 278 East. The dam would result in a 650 acre reservoir that would provide 32 million gallons of water each day (mgd), which would be sufficient for 75-100 years. The reservoir would be surrounded by a 100 foot natural vegetation buffer (no build area). Access to the reservoir would be limited, similar to the Lake Catoma ordinance.
