Sysladobsis Lake dam
Sysladobsis Lake
Sysladobsis Lake, also known as Dobsis Dam, is a mesmerizing water resource nestled in Grand Lake Stream, Maine. This private lake is fed by the West Branch St. Croix River and serves as a vital hydroelectric source with a dam type classified as Earth. The dam, completed in 1861, stands at a height of 9 meters and spans 250 meters in length, boasting a storage capacity of 123,555 acre-feet and a surface area of 5,400 acres.
Managed by the Federal Energy Regulatory Commission, Sysladobsis Lake presents a low hazard potential despite its very high risk assessment ranking. The controlled spillway, outfitted with two slide gates, ensures efficient water flow management. Although the condition assessment is not available, the lake's emergency action plan and risk management measures contribute to its overall safety and operational efficacy. With its serene beauty and hydroelectric significance, Sysladobsis Lake stands as a captivating destination for water resource and climate enthusiasts alike.
This picturesque lake in Washington County, Maine, offers a glimpse into the intricate balance between nature and human intervention. As a primary source of hydroelectric power, Sysladobsis Lake plays a crucial role in the region's energy infrastructure. With its rich history dating back to the 19th century, this Earth dam continues to provide sustainable energy solutions while maintaining a harmonious relationship with its surrounding ecosystem. Discover the allure of Sysladobsis Lake and witness firsthand the intersection of innovation and environmental stewardship in this breathtaking water resource.

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 Sysladobsis Lake
Where does the data for Sysladobsis 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 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.
