WINDSOR UPPER DAM IMPROVEMENTS

FIXING AN OLD DAM

When Tropical Storm Irene roared through Windsor in 2011, the deluge of water it released nearly collapsed the already structurally fragile, Windsor Dam. A civil engineering and historic landmark, the dam is close to its 200 year anniversary and was in need of significant upgrades. We provided the engineering design, testing, phasing and careful planning required to update it. Customized solutions were implemented that reinforced and stabilized it and also preserved its historical character.

WINDSOR UPPER DAM IMPROVEMENTS

The Windsor Upper Dam (aka The Ascutney Mill Dam) has stood for 185 years in Windsor, Vermont and is among the earliest storage dams built in the United States. It is recognized by the American Society of Civil Engineers as an engineering landmark and is listed on the National Register of Historic Places. In response to concerns raised in 2010, the town conducted a regular level inspection that identified several structural and hydraulic deficiencies, threatening its future.

Subsequent annual inspections indicated these deficiencies to be worsening—especially following Tropical Storm Irene—in 2011 with significant overtopping and loss of buttress shell masonry. Financial limitations led the town to choose an incremental repair approach that prioritized a balance between funding resources and best‐value risk reduction.

Some of the main challenges of the project included:
