Daily monitoring is discontinued because Point of Rocks flow has well exceeded the low flow monitoring threshold. Also, the observed precipitation over the past 48-hours has equaled 1 to 6 inches across most locations in the basin, and the forecast includes additional precipitation in the near future. Thank you all for your contributions to the monitoring effort.
The October Water Supply Outlook, which reports on water conditions in the basin, will be published sometime next week when the available data reflects the recent precipitation in the basin.
