ALERT: November 15 update on the status of the nationwide data transmission error preventing stream gauge data collected at affected locations from being displayed on the Advanced Hydrologic Prediction Services (AHPS) webpages. As of 11/08/2018, The USGS has restored all impacted operational stream gauges to transmitting status. The status map of gauge outages from other agencies is here. The outage map will be updated each Thursday. We apologize for the service interruption and hope to have the data restored as soon as possible.

26 Major lowland flooding closes many streets and roads. Much of the city park downstream floods. Lowest homes above Georgetown to Granger Lake are threatened.
23 Moderate lowland flooding inundates many secondary and primary roads near the San Gabriel River. Facilities and equipment well into the flood plain are flooded. Residents of lowest homes in the flood plain above Georgetown to Granger Lake should monitor NOAA Weather Radio for developing heavy rain and flood conditions.
20 Moderate lowland flooding closes secondary and primary roads near the river. The city park is severely flooded. Livestock and equipment should be moved from the flood plain from the headwaters to Granger Lake.
17 Moderate lowland flooding inundates many secondary and primary roads near the San Gabriel River from the headwaters of the South Fork to Granger Lake. The city park in Georgetown and any facilities and equipment in the flood plain are damaged.
13 Moderate lowland flooding inundates secondary roads and low bridges. Flow enters the lowest areas of the city park.
9 Minor lowland flooding reaches low areas of the flood plain with no significant damage. Lowest areas of the city park downtown are flooded.
5 Flow exceeds lowest sections of the banks.
