Dam 46 dam
Dam 46
Dam 46, also known as Pershing Lake, is a Federal-owned structure located in Killeen, Texas. Managed by the US Army, this earth dam stands at 49 feet tall and stretches for 3710 feet, providing a storage capacity of 4758 acre-feet. With a spillway width of 350 feet and a surface area of 30 acres, Dam 46 plays a crucial role in controlling water flow and mitigating flood risks in the region.
Constructed by the USDA NRCS, Dam 46 is regulated by the Texas Commission on Environmental Quality (TCEQ) and undergoes regular inspections to ensure its safety and functionality. Considered to have a high hazard potential, this dam has a moderate risk rating and an Emergency Action Plan in place. Despite its age and condition assessment being unavailable, Dam 46 continues to serve its primary purpose of water storage and flood control effectively, showcasing the dedication of the US Army in managing critical water resources in the area.
For water resource and climate enthusiasts, Dam 46 presents an intriguing example of federal infrastructure designed to safeguard communities from the impacts of extreme weather events. As a key component of the local water management system, this earth dam stands as a testament to the collaborative efforts of various agencies, including the US Army and NRCS, in ensuring the resilience of water resources in Bell County, Texas. With its impressive storage capacity and strategic location, Dam 46 remains a vital asset in the region's efforts to adapt to changing environmental conditions and protect against potential hazards.

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 46
Where does the data for Dam 46 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 High 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.
