USGS Water-Year Summary 2024
11336600 Delta Cross Channel near Walnut Grove, CA
LOCATION - Lat 38°14'41", long 121°30'19" referenced to North American Datum of 1983, Sacramento County, CA, Hydrologic Unit 18040012,
DRAINAGE AREA - Indeterminate
REVISIONS HISTORY -
On 3/3/2020 the Discharge and Tidally-filtered discharge time series were revised. During periods when the Delta Cross Channel gates are closed, the computed discharge values are published as "zero". This impacts all down-chain time series. Tidally filtered discharge was recomputed with those updated "zero" values. The only data that changed were during periods that the gates were closed.
On 12/20/2024 the mean tidally-filtered discharge time series was revised. These values were not recomputed on 3/3/2020 following the change to the revisions discussed above. The only changes are periods impacted by gate closures.
SURFACE-WATER RECORDS
REMARKS - The US Bureau of Reclamation (USBR) operates a set of radial gates at the Delta Cross Channel. When those gates are in the closed position, we estimate zero flow through the channel. These periods are marked as "estimated" when the records are analyzed and approved.
