MARFC's 24-hour accumulated precipitation map is showing that scattered areas in the basin received 0.1 to 1.75 inches of rain yesterday. The 3-day forecast shows an accumulation between 0.1 and 0.75 is possible, with the higher amounts likely to the southwest.
The USGS visited the Point of Rocks gage yesterday to verify the rating curve. Flow was measured as slightly less than what the gage was reporting.
