Galvan No 2 Pit Dam dam
Galvan No 2 Pit Dam
Galvan No 2 Pit Dam is a private-owned earth dam located in Webb County, Texas, specifically on the Santa Isabel Creek. Standing at a height of 14 feet and stretching 1070 feet in length, this dam provides a storage capacity of 78 acre-feet, with a normal storage level of 64 acre-feet. With a surface area of 5.4 acres, this dam plays a crucial role in managing water resources in the area, especially during periods of high discharge.
Despite its relatively small size, Galvan No 2 Pit Dam is classified as having a high risk potential, signaling the importance of consistent monitoring and maintenance. With one outlet gate and no spillway, this dam presents unique challenges for flood control and emergency response strategies. While its condition is currently not rated, the dam's risk assessment highlights the need for proactive risk management measures to ensure the safety and integrity of this essential water resource infrastructure.
For water resource and climate enthusiasts, Galvan No 2 Pit Dam offers a fascinating case study in the complexities of dam management and the critical role these structures play in sustaining local water supplies. With its strategic location on the Santa Isabel Creek and its significant storage capacity, this dam serves as a vital component in the region's water management system. As efforts to address climate change intensify, understanding and effectively managing dams like Galvan No 2 Pit Dam will be crucial in adapting to shifting weather patterns and ensuring sustainable water resources for future generations.

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 Galvan No 2 Pit Dam
Where does the data for Galvan No 2 Pit 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.
