About this dam

Baltic Reservoir Dam (West)

The Baltic Reservoir Dam (West) in Connecticut, situated on the Shetucket River Tributary, stands as a vital structure for water supply in the region. Owned by the local government, this buttress dam stands at a height of 30 feet and stretches 160 feet in length, with a reservoir capacity of 305 acre-feet. Completed in 1900, the dam serves as a key component in maintaining water resources for the community in Sprague.

With a spillway width of 160 feet and a maximum discharge of 110 cubic feet per second, the Baltic Reservoir Dam is equipped to manage significant water flow during periods of heavy precipitation. Despite its age, the dam has been assessed as satisfactory in condition, with a moderate risk assessment assigned. Regular inspections every five years ensure that the dam continues to operate effectively and safely, meeting state regulations and enforcing necessary measures to mitigate potential hazards.

As a critical piece of infrastructure in the region, the Baltic Reservoir Dam plays a crucial role in water resource management and climate resilience. Its presence supports the community by providing a reliable water supply while also safeguarding against flooding events through its controlled spillway system. With a commitment to ongoing maintenance and risk management, this dam remains a cornerstone in protecting and sustaining water resources in the area.

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.

FAQ

About Baltic Reservoir Dam (West)

Where does the data for Baltic Reservoir Dam (West) 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.
