Naji Lake Dam dam
Naji Lake Dam
Naji Lake Dam, located in Mechanicsville, Ohio, is a privately owned earth dam completed in 1963 for the primary purpose of recreation. The dam stands at a height of 18.7 feet and has a storage capacity of 85.2 acre-feet, with a normal storage level of 20.7 acre-feet. The dam holds back Mill Creek, contributing to a drainage area of 2.36 square miles and covering a surface area of 6.2 acres.
Despite its recreational importance, Naji Lake Dam poses a high hazard potential due to its poor condition assessment as of the last inspection in March 2016. The dam's emergency action plan (EAP) status is unclear, and there are no inundation maps prepared to outline potential risks in case of a failure. With a history of repairs in 1977 by Robert E. Phillips from Chardon, Ohio, the dam remains under the regulatory oversight of the Ohio Department of Natural Resources, indicating state permitting, inspection, and enforcement protocols are in place.
Water resource and climate enthusiasts interested in Naji Lake Dam will find it to be a significant structure in Ashtabula County, Ohio, serving both recreational and flood control purposes. The dam's location along Mill Creek within the Pittsburgh District adds to its regional importance. However, concerns over the dam's high hazard potential and poor condition assessment highlight the need for continued monitoring and maintenance to ensure the safety of surrounding communities and the preservation of this valuable 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 Naji Lake Dam
Where does the data for Naji Lake 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.
