Grandview Wastewater Lagoon F Dam dam
Grandview Wastewater Lagoon F Dam
Grandview Wastewater Lagoon F Dam, located in Yakima, Washington, is a significant structure owned by the local government and regulated by the Washington Department of Ecology. This buttress dam, completed in 1997, serves a primary purpose categorized as "Other," with a hydraulic height of 8.8 feet and a storage capacity of 128 acre-feet. The dam stands at a structural height of 8.8 feet and has a length of 100 feet, controlling the flow of the Yakima River.
The dam's condition was last assessed in July 2019 and deemed satisfactory, with a significant hazard potential. It undergoes inspection every five years to ensure its operational integrity and safety. The dam's Emergency Action Plan (EAP) was last revised in July 2019, aligning with guidelines for risk management and emergency preparedness. With a drainage area of 0.63 square miles, the Grandview Wastewater Lagoon F Dam plays a crucial role in water resource management in the region, highlighting the importance of maintaining and monitoring its condition for climate resilience and public safety.
As a key infrastructure in the water management system, Grandview Wastewater Lagoon F Dam stands as a testament to the collaborative efforts between local government agencies and state regulators to safeguard water resources and mitigate potential risks. With its storage capacity, structural design, and regulatory oversight, the dam serves as a vital component in ensuring water security in the Yakima area. As water resource and climate enthusiasts, understanding the significance of structures like the Grandview Dam underscores the importance of sustainable water management practices to address the challenges posed by changing environmental conditions.
Dam data reference
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 Grandview Wastewater Lagoon F Dam
Where does the data for Grandview Wastewater Lagoon F 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 Significant 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.
