Harrell Levee 1 dam
Harrell Levee 1
Harrell Levee 1, located in McCulloch County, Texas, was completed in 1940 and serves primarily for irrigation purposes. The earth dam stands at a height of 11 feet and has a storage capacity of 60 acre-feet. With a surface area of 6 acres, the levee is situated off Ch-Tr-Brady Creek, under the jurisdiction of the Fort Worth District of the US Army Corps of Engineers.
Despite being privately owned and not regulated by the state, Harrell Levee 1 poses a high risk due to its outdated infrastructure and lack of recent inspections. The dam's condition is currently not rated, and emergency preparedness measures such as an emergency action plan have not been documented. It is crucial for water resource and climate enthusiasts to advocate for the proper maintenance and assessment of this levee to prevent potential hazards and ensure the safety of surrounding areas.
As a key structure for irrigation in the region, the significance of Harrell Levee 1 cannot be underestimated. Its role in water resource management underscores the importance of regular inspections, risk assessments, and adherence to safety guidelines. With its historical context and current risk level in mind, it is essential for stakeholders to prioritize the upkeep and monitoring of this levee to safeguard both the water supply and the community it serves.

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 Harrell Levee 1
Where does the data for Harrell Levee 1 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.
