Notes

Water is pooled and not running into The Dollis. Looks very scummy and is in shade, although water clear under the surface scummy Due to drought conditions and no rainfall for 8 weeks, Folly Brook is not fully running from Darlands, dry sections with some pools in places. Outfall Foly0003 upstream is polluting
