Storage data for Lake Almanor is initially determined by PG&E
from a PG&E gauge located near Prattville. This storage data
is then transmitted to the California Department of Water Resources (DWR)
and posted daily on the
DWR website.
PG&E/DWR data is preliminary and subject to later revision by the U. S.
Geological Survey (USGS). USGS
daily storage
data for Lake Almanor is published annually as USGS gage 11399000 "Lake Almanor at
Prattville, CA". USGS Lake Almanor storage data is available from
1913 but much is not available online. Some of the early data
is monthly storages.
