FLOW MONITORING

A device to monitor the instream flow requirement is a standard condition that the Division of Water Resources requests in a license, permit or certificate for water withdrawals or dams. Rule .0504 for the N.C. Dam Safety Law requires a gage to be installed and rated every two years, in accordance with U.S. Geological Survey (USGS) Paper No. 2175, for any subject dam. A gage needs to be recalibrated every two years to verify the accuracy of the rating curve.

Gages allow the water user to determine if he is releasing enough water below a dam, if the water surface elevation in a reservoir is high enough or if there is enough water flowing by a water withdrawal structure. Gages allow private citizens or resource agencies to verify compliance with flow requirements. Gages also allow recreational users to determine stream flows suitable for water-based activities.

The gage is typically a graduated, enamel-coated, metal plate that is permanently affixed in the stream channel and rated, such that the water surface elevation corresponding to the flow requirement is known and can be compared to the gage. The gage may also be a float that is attached by a wire to a continually recording drum, disk, or punch tape on site or transmission via satellite to a distant computer.

The cost of installation, rating and maintenance of a gage is assumed by the water user. A private consultant, or the USGS, may establish the gage. The cost of maintaining most real-time gaging stations is through cooperative agreements between the USGS and other federal agencies, North Carolina agencies, public utilities, private corporations and local governments.

Failure to monitor and comply with instream flow requirements can be reported to the N.C. Division of Land Resources Dam Safety Program (Dam Safety Permit), the Federal Energy Regulatory Commission (Hydropower License or Exemption), U.S. Army Corps of Engineers (404 Permit), the N.C. Division of Water Quality (401 Certificate), the N.C. Utility Commision (Certificate of Convenience and Necessity), the U.S. Fish and Wildlife Service, or the N.C. Wildlife Resources Commission.
