Low water flow recorded near Pasadena
Streamflow Situation from the network of US Geological Survey in California
Water levels are getting lower in the North Coast, San Francisco, Central Coast and Los Angeles watersheds. Monitoring stations currently recording flows below the 10th percentile, much below normal to low ratings are becoming more common as the wildfire situation continues.
Arroyo Seco monitored near Pasadena is recording an extreme low flow level, first percentile, running just one foot deep at a trickle, less than one cubic foot per second. Looking at the flow data for the last two months, this water body does not get much above 1 ft, however we have not seen this low flow rating until today. California Data Exchange Center shows the reservoir storage levels in the Los Angeles Region 4 basin, we have inquired of water wholesaler for Los Angeles County more information on the water supply available for the wildfire fighting efforts. More to follow.
As reported yesterday, Metropolitan Water District of Southern California is the regional water wholesaler, according to spokesperson Rebecca Kimitch, "we import water from two sources – the Colorado River and northern California – and then deliver it to our 26 member agencies." We are at this time seeking more information as to other reservoirs in the watershed area that can divert flow to the wildfire zone.
