Mckinney Lake Dam dam
Mckinney Lake Dam
Mckinney Lake Dam, located in Archer County, Texas, is a privately owned earth dam that was completed in 1964 for recreational purposes. With a height of 21 feet and a length of 720 feet, the dam provides a storage capacity of 227 acre-feet for McKinney Lake. The dam is situated on TR-ONION CREEK and is under the jurisdiction of the Fort Worth District of the US Army Corps of Engineers.
Although the dam has no spillway and a hazard potential that is not available, it is important to note that the risk assessment for the dam is considered high. The condition of the dam is currently not rated, and it lacks an emergency action plan as well as updated inundation maps. Despite these shortcomings, the dam continues to serve as a popular recreational spot for visitors in the area.
As water resource and climate enthusiasts, it is crucial to monitor and assess the safety and maintenance of dams like Mckinney Lake Dam to mitigate potential risks and ensure the protection of surrounding communities and ecosystems. The dam's risk assessment, high hazard potential, and lack of crucial emergency preparedness measures highlight the importance of ongoing evaluation and proactive measures to safeguard water resources and prevent potential disasters.

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 Mckinney Lake Dam
Where does the data for Mckinney 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 Not Available 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.
