...New River Forecast Point: Kernville, Kern County...

TO: Subscribers: Emergency Management Officials…News Media…and Other Users

SUBJECT: New River Forecast Point: Kernville, Kern County

The National Weather Service (NWS) Hanford (HNX) office has created a new
river forecast point for the Kern River in Kern County. In August
of 2023, the NWS Hanford Hydrology team conducted a survey of the
Kernville gage at Kern River in Kern County, and determined that
the town of Kernville experiences flood impacts beginning when the
Kern River reaches 13.5 feet in depth. Kernville saw many flood
impacts over the past winter with the historic rainfall that
occurred. As such, from a meteorological, hydrological, and
dissemination standpoint, the creation of a river forecast point
and flood stages along the Kern River at Kernville will better
serve NWS customers in Kern County and the towns of Kernville and
Riverkern. Effective Wednesday, November 1, 2023, the National
Weather Service plans to incorporate this new river forecast point
into our flood messaging and products, alongside the other five
established river forecast points our office manages.

For the Kernville river forecast point, monitor/action stage will
be 12.5 feet, flood stage will be 13.5 feet, moderate flood stage
will be 17.5 feet, and major flood stage will be 20 feet. Below
are the flood stages with the corresponding flood impacts seen by
the Kernville community.
