Mosquito Creek Dam dam
Mosquito Creek Dam
Mosquito Creek Dam, also known as Mosquito Creek Lake, is a Federal-owned structure located in Trumbull County, Ohio. Completed in 1944 by the US Army Corps of Engineers, the dam serves as a flood risk reduction measure along the Mosquito Creek. Standing at a structural height of 47 feet with a total length of 5650 feet, the dam has a storage capacity of 180,000 acre-feet and covers a surface area of 7850 acres.
Despite its risk management measures, the dam poses a high hazard potential with a moderate risk assessment due to the possibility of erosion of its soil foundation during high reservoir levels. If a breach were to occur, downstream communities such as Warren and Niles could face swift and deep floodwaters, potentially resulting in the destruction of buildings and key infrastructure. To mitigate these risks, the US Army Corps of Engineers continues to work closely with state and local emergency managers, conduct emergency exercises, monitor the dam rigorously, and provide flood warnings based on rainfall forecasts.
In the event of high reservoir levels, the public can access current and forecasted lake levels at Pittsburgh District reservoirs through the US Geologic Survey and the National Weather Service. By engaging with local communities and providing flood preparedness information, the dam aims to enhance public awareness and readiness for potential flood events, ensuring the safety of residents in the surrounding areas.

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 Mosquito Creek Dam
Where does the data for Mosquito Creek 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 High 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.
