The RainMap provides more information than just rain. You can choose several different datasets including "Water Level" which shows the water level on the the gauges we maintain in Contra Costa County. We've added 10 new stream gauges under a grant from DWR. We should have a couple more on the map before the start of winter. The primary goal of these new stream gauges is to assist in flood warning. We will eventually adjust the readings to correspond to an elevation relative to the flood stage and possibly flood warning and flood watch levels.
