Glendale dam
Glendale
Glendale is a historic hydroelectric dam located in Great Barrington, Massachusetts, along the picturesque Housatonic River. Built in 1906, this gravity dam stands at 30 feet tall and stretches 250 feet in length, providing a storage capacity of 87 acre-feet. With a maximum discharge rate of 9000 cubic feet per second, Glendale is a vital infrastructure for not only electricity generation but also water resource management in the region.
Managed by the Federal Energy Regulatory Commission, Glendale has a low hazard potential and a moderate risk assessment rating of 3. Despite its age, the dam remains in good condition with regular inspections, including the recent one in May 2018. The dam's uncontrolled spillway, with a width of 182 feet, ensures proper water flow during periods of excess. Its location within the New England District makes it an important contributor to the local ecosystem's hydrological balance and a significant piece of infrastructure for climate enthusiasts and water resource management professionals.
As a gravity dam with a primary purpose of hydroelectric power generation, Glendale showcases the harmonious blend of human ingenuity with environmental stewardship. Its role in providing renewable energy and regulating water flow in the Housatonic River highlights the crucial intersection between water resources and climate resilience. With its historical significance and ongoing operational importance, Glendale stands as a testament to the enduring value of sustainable infrastructure in mitigating the impacts of climate change on water ecosystems.
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 Glendale
Where does the data for Glendale 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 Low 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.
