Moderate flooding of local streams and the nearby Millstone River. The Millstone at Blackwells Mills is running higher than either of the March crests and is still rising. I've noted "unusual street or field flooding" at the bottom of this form as this does not qualify as "minor/typical". However it occurs more than every few years....witness twice last month. I think the issue is more with the choices on the form rather than the frequency of the flooding that has occurred (not that it hasn't been quite the siege of late).
