Duke Energy Carolinas to increase Nantahala water flow

On Thursday, January 2, 2014 after 4:00 pm, Duke Energy will open a Tainter gate at Nantahala Dam releasing approximately 400 cfs.  Duke Energy has a Federal Energy Regulatory Commission (FERC) requirement to complete maintenance on all the Tainter gates at Nantahala Dam and needs to lower the lake level to below the bottom of the Tainter gates.  Due to abundant rainfall, the natural inflow into the reservoir is greater than what can be passed by running the generating unit 24 hours per day.  Running the generator 24 hours per day is not lowering the lake level to accommodate the FERC required work.

The generator will continue to run 24 hours a day.  The Tainter gate will remain open till the lake level is below the bottom of the Tainter gate.  Spillage from the Tainter gate will increase the flow in the bypass reach from the Nantahala Dam to the Nantahala Powerhouse. As always, the general public and members of the rafting/outfitters community on the Nantahala River are strongly encouraged to monitor the USGS Streamflow Gauge at Hewitt for the most current flow information.http://waterdata.usgs.gov/nc/nwis/uv/?site_no=03505550&PARAmeter_cd=00065,00060

Because of the potential to impact the fishing public, we will make the release such that the water will arrive in the delayed harvest section of the bypass reach area at night.  The following message will be posted today so, the public will have a chance to plan accordingly:

The Nantahala River Basin has had significant rainfall over the last two weeks.  A spillway gate will be partially opened the afternoon of Thursday, January 2nd.  We expect that gate to remain partially open for several days.  WARNING: high flows and the natural environment of the bypassed reach can create dangerous conditions for paddlers and fly fishermen.  Duke Energy will continue to closely monitor conditions.  Updated lake levels are available any time at http://www.duke-energy.com/lakes/levels.asp  and at 800-829-5253.  As always, we encourage those living along lakes, streams and other low-lying and flood-prone areas to pay special attention to changing weather conditions and take any necessary precautions. We will provide additional updates if conditions change.
