West Hill Dam - Dike D dam
West Hill Dam - Dike D
West Hill Dam - Dike D, also known as Dry Reservoir, is a gravity dam located in Uxbridge, Massachusetts, along the West River. Built in 1961 by the US Army Corps of Engineers, the dam serves as a flood risk reduction measure, with a structural height of 48 feet and a length of 2400 feet. The dam has a maximum storage capacity of 29,500 acre-feet and a maximum discharge of 8,900 cubic feet per second.
The dam is classified as having a high hazard potential, and the US Army Corps of Engineers actively manages dam-related flood risks by monitoring the dam's condition, prioritizing risk-reduction activities, and engaging with local emergency managers and the public to raise awareness and preparedness. The emergency action plan for the dam is regularly updated, and maintenance and repairs are performed as needed to ensure the dam's proper functioning. Despite these measures, the dam may release water to manage levels and prevent structural issues during severe weather events or periods of high water inflow.
Overall, West Hill Dam - Dike D plays a crucial role in flood risk reduction in the area, and the US Army Corps of Engineers is dedicated to ensuring the safety and integrity of the dam through proactive risk management and maintenance practices. The dam's impact on the surrounding environment and communities is carefully monitored and managed to prevent and mitigate potential issues related to flooding and water management.

Condition Assessment
- Satisfactory
- No existing or potential dam safety deficiencies are recognized. Acceptable performance is expected under all loading conditions (static, hydrologic, seismic) in accordance with the minimum applicable state or federal regulatory criteria or tolerable risk guidelines.
- Fair
- No existing dam safety deficiencies are recognized for normal operating conditions. Rare or extreme hydrologic and/or seismic events may result in a dam safety deficiency. Risk may be in the range to take further action.
- Poor
- A dam safety deficiency is recognized for normal operating conditions which may realistically occur. Remedial action is necessary. POOR may also be used when uncertainties exist as to critical analysis parameters which identify a potential dam safety deficiency.
- Unsatisfactory
- A dam safety deficiency is recognized that requires immediate or emergency remedial action for problem resolution.
- Not Rated
- The dam has not been inspected, is not under state or federal jurisdiction, or has been inspected but, for whatever reason, has not been rated.
Hazard Potential Classification
- High
- Dams assigned the high hazard potential classification are those where failure or mis-operation will probably cause loss of human life.
- Significant
- Dams assigned the significant hazard potential classification are those dams where failure or mis-operation results in no probable loss of human life but can cause economic loss, environmental damage, disruption of lifeline facilities, or impact other concerns. Significant hazard potential classification dams are often located in predominantly rural or agricultural areas but could be in areas with population and significant infrastructure.
- Low
- Dams assigned the low hazard potential classification are those where failure or mis-operation results in no probable loss of human life and low economic and/or environmental losses. Losses are principally limited to the owner's property.
- Undetermined
- Dams for which a downstream hazard potential has not been designated or is not provided.

About West Hill Dam - Dike D
Where does the data for West Hill Dam - Dike D come from?
Structural and regulatory data come from the U.S. Army Corps of Engineers' National Inventory of Dams (NID). Weather forecast comes from NOAA / yr.no -- the same feed Snoflo's iOS app uses.
How often is the report updated?
NID structural data refreshes annually as the Corps publishes updated assessments. The weather forecast refreshes throughout the day.
What does the High hazard rating mean?
The Corps of Engineers' hazard potential classification grades probable consequences if the dam fails: High = probable loss of human life; Significant = no probable loss of human life but possible economic loss / environmental damage; Low = no probable loss of human life, only minor economic / environmental losses. See the Dam Data Reference card above for the full definitions.
What's "% of normal"?
The current storage value compared to the historical average storage on this calendar day. 100% = right on average; values above 100% mean above-normal storage (wet year); values below mean below-normal (dry year or drought).
Can I get alerts when storage crosses a threshold?
Yes -- alerts are managed in the Snoflo iOS app. Favorite this dam, set a threshold, and you'll get a push the moment conditions cross.
