Lake Lashaway Dam dam
Lake Lashaway Dam
Lake Lashaway Dam, located in East Brookfield, Massachusetts, is a vital structure managed by the Department of Conservation and Recreation. Built in 1926, this earth dam stands at a height of 23 feet with a hydraulic height of 17 feet, serving primarily for recreational purposes on the East Brookfield River. With a storage capacity of 3,056 acre-feet and a surface area of 25.2 acres, the dam plays a significant role in the local water resource management.
Despite being classified as having a significant hazard potential, Lake Lashaway Dam is in fair condition as of the last inspection in November 2015. The dam's capability to handle potential risks is moderate, with a risk assessment rating of 3 out of 5. The dam has a spillway type of uncontrolled, with no outlet gates or locks associated. Its inspection frequency is every five years, ensuring regular monitoring of its structural integrity and overall safety measures.
Water resource and climate enthusiasts will appreciate the historical significance and functional importance of Lake Lashaway Dam. As a key recreational site in Worcester County, Massachusetts, this structure not only provides leisure activities but also plays a crucial role in water storage and management for the surrounding area. The dam's construction and design reflect a blend of engineering expertise and environmental considerations, making it a noteworthy feature for those interested in sustainable water resource practices.
Dam data reference
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 Lake Lashaway Dam
Where does the data for Lake Lashaway Dam 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 Significant 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.
