The Still River runs through Danbury, Newtown, Brookfield and New Milford.  The Housatonic Valley Association is working with the municipalities on an EPA approved watershed plan and a draft existing conditions report on the health of the watershed.  The organization works to restore and protect the 2,000 square miles of the Housatonic watershed.  Conservation Projects Manager Courtney Moorehouse says the Still River is buried in a few places in Danbury and is channelized in other places.  She says it's not natural, but is reducing flooding in the downtown area.  Moorehouse says it's a good thing, from a public safety standpoint, to have that infrastructure in place.  She notes that there's not much that can be done in areas of that so-called grey infrastructure.  Moorehouse says they will work with the City, land trusts and others to improve water quality where they can.
