Or Mitchell Lake 1 Dam dam
Or Mitchell Lake 1 Dam
Or Mitchell Lake 1 Dam, located in Bexar, Texas, stands as a testament to the vital role of water resource management in the region. Built in 1967 for irrigation purposes along the Medio Creek, this earth dam reaches a height of 32 feet and spans a length of 2537 feet. Despite its age, the dam continues to serve as a crucial water storage facility, with a maximum storage capacity of 520 acre-feet and a normal storage capacity of 192 acre-feet.
Managed by the local government and regulated by the Texas Commission on Environmental Quality (TCEQ), Or Mitchell Lake 1 Dam has not been rated for its condition assessment, but is classified as having a high risk potential. This underscores the importance of regular inspections and risk management measures to ensure the safety and effectiveness of the dam. While the dam currently lacks a spillway and drainage area, it remains a key component of the region's water infrastructure, providing essential water resources for irrigation purposes.
With its strategic location and historical significance, Or Mitchell Lake 1 Dam serves as a focal point for water resource and climate enthusiasts. As a part of the Galveston District and with no federal agency involvement, the dam symbolizes the local government's commitment to water management and reflects the ongoing need for sustainable practices in the face of changing climate conditions. The dam's role in maintaining water supply and supporting agricultural needs highlights the interconnectedness of water resources, climate resilience, and community sustainability in the region.

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 Or Mitchell Lake 1 Dam
Where does the data for Or Mitchell Lake 1 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.
