...FAST FLOWING COLD WATER IN AREA RIVERS AND STREAMS IS
DEADLY RIGHT NOW...
With record breaking heat across the Central California
Interior...area rivers, lakes and streams are at very high
levels due to the extensive winter snow pack melting at a very
As we enter the summer recreation season, the National Weather
Service would like to remind people of the hidden dangers of the
cold snow melt waters feeding Central California waterways.
Area rivers, streams and reservoirs are directly fed from the
melting snowpack on the Sierra Nevada. Even though a stream or
river looks cool and inviting, the water is actually very cold
ranging from 45 to 55 degrees Fahrenheit. Outdoor enthusiasts are
advised to use extreme caution near rivers, streams and lakes. If
possible please avoid these areas all together.
If you are planning to travel to area rivers and streams,
remember that the fast flowing and very cold water is a deadly
combination. Although afternoon temperatures are expected to be
100 to 110, water temperatures are in the upper 40`s to lower
50`s. Up to fifteen minutes exposure to water this cold could lead
to hypothermia, and the fast flow of the river can easily carry a
rafter or swimmer quickly downstream...which can and has led to
Hypothermia is a sudden loss of body temperature that can be
fatal. Warning signs include uncontrolled shivering, slurred
speech, drowsiness and apparent exhaustion. Even strong swimmers
can tire quickly in the cold water. When you add a strong current
and underwater debris, such as rocks, limbs and sharp objects,
drowning becomes more likely.
River fluctuations can and will occur without notice. River
levels can change very quickly depending on upstream dam releases
and debris in the rivers and streams, creating partial blocking
of the water flow. If you are only near the edge of the river or
stream, you could slip and fall. Don`t turn your back on the
river or stream.
Central California rivers and streams are Swift! Cold! and
Dangerous! Many people have already lost their lives across the
Central California Interior due to drowning in area rivers and
streams. Please have life vests handy and keep a close eye on
children and pets near the rivers edge.
