Pond Gw-11 Dam dam
Pond Gw-11 Dam
Pond Gw-11 Dam, located in Henderson, Nevada, is a privately-owned structure designed by Western States Engineering and completed in 1998. This earth dam stands at a height of 23 feet and serves as a vital component in managing water resources in the region. With a storage capacity of 114 acre-feet and a normal storage level of 50 acre-feet, the dam plays a crucial role in regulating the flow of the Las Vegas Wash-OS river or stream.
The dam's primary purpose is categorized as "Other," indicating its multifaceted role in water management. Despite being classified as having a high hazard potential, the dam is currently assessed to be in fair condition as of the last inspection in October 2021. With an emergency action plan in place and regular inspections, the dam is equipped to handle any unforeseen events and ensure the safety of the surrounding area. Additionally, the risk assessment categorizes the dam as high risk, emphasizing the importance of proactive risk management measures.
As a significant feature in the water infrastructure of Clark County, Nevada, Pond Gw-11 Dam stands as a testament to the collaborative efforts of private entities and state regulatory agencies in ensuring the effective management of water resources. With its strategic location and design, the dam plays a crucial role in mitigating flood risks, regulating water flow, and safeguarding the surrounding environment. For water resource and climate enthusiasts, Pond Gw-11 Dam serves as a fascinating case study in the intersection of engineering, regulation, and environmental stewardship.

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 Pond Gw-11 Dam
Where does the data for Pond Gw-11 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 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.
