Public Warning System
For the safety of all those who use the Cheat Lake facility, a 1,000-foot
exclusion zone is marked by warning buoys upstream of the Lake Lynn
dam. Four red warning lights provide warnings to boaters on the
lake that they are nearing the dam.
Additionally, a public warning system for rapidly rising water
on the Cheat River has been installed in the first mile of the tailrace
below the dam. Lights and speakers are located both near the powerhouse
and along the riverbank. A 1,200-foot (400-yard) exclusion zone
will be maintained downstream of the dam. Please be alert to the
following conditions and warnings:
- Warning for minor flow increases: Continuous yellow lights and
a series of single tones - Caution is urged.
- Warning of more significant flow increases: Red light and a
series of double tones followed by a pre-recorded voice message
- Rapid rise expected. Leave the water immediately.
The red-light warning system is used in the following circumstances:
- Three minutes prior to the start-up of generation. (This includes
the 1,200-foot exclusion zone.)
- Fifteen minutes prior to opening a trash gate.
- Fifteen minutes prior to the beginning of any tainter gate opening
operations scheduled during high-flow conditions. (Once started,
the warning will be repeated every 10 minutes until the station
operator determines that no further tainter gate operations will
be needed.)
- Any time a station operator witnesses a violation of the exclusion
zone.
- Any other time the station operator believes the need arises.
