Old Mill Creek Dam dam
Old Mill Creek Dam
Old Mill Creek Dam, located in Montgomery, Texas, is a privately owned earth dam primarily used for recreation. Completed in 2004, the dam stands at a height of 12 feet and has a storage capacity of 50 acre-feet. Situated on the TR-Mill Creek, this dam is regulated and inspected by the Texas Commission on Environmental Quality (TCEQ), ensuring its safety and compliance with state regulations.
Despite being classified as having a high risk potential, the condition of Old Mill Creek Dam is currently not rated. The dam does not have a spillway and is equipped with one outlet gate. While its hazard potential is not available, the dam raises concerns due to its high-risk classification. The last inspection was conducted in 2004, and no Emergency Action Plan (EAP) has been prepared, indicating a need for improved risk management measures and emergency preparedness.
Enthusiasts of water resources and climate will find Old Mill Creek Dam an intriguing subject due to its unique design as an earth dam with buttress core types. The dam's location on the TR-Mill Creek adds to its appeal for outdoor recreation activities. Despite its risk potential, the dam's history and structural details provide valuable insights into the intersection of human infrastructure with natural water systems in the context of climate change and water resource management.

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 Old Mill Creek Dam
Where does the data for Old Mill 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 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.
