Connecticut Streamflow Overview
Know The Flow!
(Please note this was written before the rain events of Mar 29-30. This page will be updated soon)
Mar 28, 2014 Summary: According to The Advanced Hydrological Prediction Service of the National Weather Service, Connecticut rainfall during the last 30 days (as of March 28) was less than 50% of normal for the entire state, with one area less than 25% of normal. Connecticut rainfall during the last 60 days showed most of the state below 75% of normal with the rest of the state below 90% of normal. The US Geological Service streamflow map of Connecticut shows only 1 in 10 streams and rivers (all in southwest CT) flowing anywhere near normal, most streams are more than 50% below average with about a third of our streams are less than 20% of normal flow for this time of year. However, ALL flows have been steadily dropping and as Fri Mar 28 all of them are now at or below the actual numerical long term average for that site.
Hopefully the short and long range forecasts that show a decent amount of rainfall for the next two weeks will prove accurate, or all of the streams in CT will soon show the orange and red of below average flow. Though groundwater levels are mostly at or above levels expected for this time of year due to snowmelt, once all the snow has melted streamflow will drop rapidly unless we get significant rainfall. The groundwater station for southwest CT is below average, so their streamflow may drop faster than the rest of the state. The US Drought Monitor map of Connecticut shows that as of Tuesday Mar 25, only about 19% of the state was classified in abnormally dry conditions, but that will change if precipitation remains below normal.
