Chambers Lake dam
Chambers Lake
Chambers Lake, also known as Federalsburg Dam, is a gravity dam located in Caroline, Maryland, with a primary purpose of water supply. Completed in 1937, this dam stands at a height of 11 feet and has a length of 390 feet, providing a storage capacity of 78 acre-feet. The lake covers a surface area of 9.4 acres and drains an area of 5.3 square miles, with a maximum discharge of 466 cubic feet per second.
Despite its age, Chambers Lake is regulated by the Maryland Dam Safety agency, with regular inspections to ensure its safety and functionality. However, the dam is currently assessed as being in poor condition, with a significant hazard potential. The emergency action plan for the dam was last revised in 2019, indicating that risk management measures may need to be updated to address the moderate risk level associated with the dam.
Water resource and climate enthusiasts interested in Chambers Lake will find a historical gravity dam that plays a crucial role in water supply for the region. The dam's location on Tanyard Branch, its controlled spillway system, and the presence of slide gates for water release all contribute to its significance in managing water resources in the area. With ongoing assessments of its condition and risk level, Chambers Lake serves as a focal point for understanding the intersection of infrastructure, environment, and water management in Maryland.

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 Chambers Lake
Where does the data for Chambers Lake 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.
