Dam E2 dam
Dam E2
Dam E2, located in Hallsville, Texas, is a private earth dam built in 1994 primarily for tailings purposes along the TR-Clark Creek. Standing at a height of 24.5 feet with a length of 1800 feet, this dam has a storage capacity of 355 acre-feet and serves the local area by controlling water flow and providing flood protection. Despite being privately owned, the dam is permitted and inspected by the state regulatory agency, ensuring its safe operation.
With a spillway width of 89 feet and a maximum discharge of 6881 cubic feet per second, Dam E2 has emergency action plans in place to manage any potential risks. The dam has been rated as moderate in terms of risk assessment, indicating a need for ongoing monitoring and maintenance to prevent any potential hazards. The structure is equipped with outlet gates for water release and is designed to withstand the hydraulic pressures of the surrounding area, making it an important component of the local water resource management system in Harrison County, Texas.
Overall, Dam E2 plays a crucial role in water management for the region, providing essential flood control and water storage capabilities. With its strategic location and design features, this earth dam exemplifies the importance of sustainable infrastructure for addressing the challenges of climate change and water resource management in Texas. As climate enthusiasts and water resource professionals continue to monitor and assess the impact of dams like E2, it serves as a reminder of the vital role that such structures play in ensuring the safety and security of communities in the face of changing environmental conditions.

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 Dam E2
Where does the data for Dam E2 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.
