Mad River Waterbury (Woodtick) Local Protection Project

Mad River Lake in WinchesterWaterbury is located approximately 20 miles north of New Haven and about 25 miles southwest of Hartford.

Flooding conditions along the Mad River in the Woodtick area of Waterbury have been aggravated by increased development in the floodplain, along with the resulting accumulation of silt and debris in the channel over the past decade.

A flood damage reduction project consisting of channel widening along two areas of the Mad River was constructed in 1996-1997. The completed flood protection project consists of improvements at Site 1 and Site 2 as more fully described below.

Site 1 improvements are a 400 foot reach located upstream of Frost Road Bridge. It consists of a widened channel and a two-foot stone protection layer underlain by a  one-foot stone bedding layer on the left bank. The stone protection is placed on a one-foot vertical to two-foot horizontal slope.

Site 2 improvements extend from approximately 340 feet upstream of Frost Road to approximately 700 feet downstream of Frost Road. Upstream of Frost Road they include a widened channel and a two foot stone protection layer underlain by a one foot stone bedding layer for approximately 240 feet of length on both sides of the river. Additional channel widening and debris removal extends 100 feet upstream of the stone protection. Downstream of Frost Road they include a widened channel, a modular concrete wall (180 feet long on the left bank and 210 feet long on the right bank) immediately downstream of the Frost Road bridge and intermittent reaches of two feet stone protection layer underlain by a one-foot stone bedding for approximately 500 feet downstream from the walls. All stone protection is placed on a one-foot vertical to two-foot horizontal slope.

The project was constructed by Brennan Construction Company from Shelton, Connecticut from April 1996 to August 1997 at a cost of $937,760.

The Army Corps of Engineers and Connecticut Department of Environmental Protection entered into an agreement for local cooperation for this project on June 2, 1993.
