Mcpherson Ranch Dam dam
Mcpherson Ranch Dam
Mcpherson Ranch Dam, located in Keller, Texas, is a private earth dam primarily used for recreation purposes. Completed in 2003, the dam stands at a height of 12 feet and has a length of 450 feet, creating a reservoir with a storage capacity of 32 acre-feet. The dam is situated on Tri-Harriet Creek and is regulated by the Texas Commission on Environmental Quality (TCEQ).
The dam features an uncontrolled spillway with a width of 90 feet and an outlet gate that is also uncontrolled. The condition assessment of the dam as of April 2017 was deemed fair, with a moderate risk rating. The last inspection of the dam was conducted in September 2016, with a scheduled inspection frequency of 5 years. The dam's hazard potential and emergency action plan status were not available at the time of data collection.
Despite its relatively small size, Mcpherson Ranch Dam provides a valuable recreational resource for the local community while also serving as a vital water management structure in the area. Its presence on Tri-Harriet Creek adds to the beauty of the surrounding landscape and offers opportunities for outdoor activities such as fishing, boating, and wildlife observation. As a privately owned and state-regulated dam, Mcpherson Ranch Dam exemplifies the importance of responsible water resource management and climate resilience in Texas.

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 Mcpherson Ranch Dam
Where does the data for Mcpherson Ranch 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.
