Streamflow, Drought, and Water Supply Conditions
Water supply conditions as of 6/21/2017
From Mike Roberts, DNRC Hydrologist and Jacqueline Knutson, MFWP Hydrology Technician
“A combination of average snowpack, near average temperatures, and above average spring precipitation has resulted in streamflows above average to well above average for the past 6 weeks. After last week’s above average peak flows, flows are beginning to subside.
Streamflows have continued to be well above average for the past month in response to spring weather and precipitation events.”
