Simplot Lrar Lagoon dam
Simplot Lrar Lagoon
Simplot Lrar Lagoon, located in Moses Lake, Washington, is a privately owned offstream lagoon that was completed in 2006 by Pharmer Engineering. This earth dam structure has a hydraulic height of 24 feet and a length of 1448 feet, providing a storage capacity of 67 acre-feet for water resource management. The lagoon covers a surface area of 2.7 acres and is regulated by the Washington Dept of Ecology, ensuring compliance with state permitting, inspection, and enforcement requirements.
With a low hazard potential and a condition assessment of "Not Rated," Simplot Lrar Lagoon serves a primary purpose of "Other" and is classified as an earth dam with rockfill core types and soil foundations. The lagoon plays a crucial role in water management for the Crab Creek watershed, contributing to the conservation of water resources in the region. Despite not having a designated spillway type or outlet gates, the lagoon's design and construction meet state regulatory standards for water storage and management.
For water resource and climate enthusiasts, Simplot Lrar Lagoon offers a fascinating case study in private water infrastructure development and management. Its strategic location in the Moses Lake area and affiliation with the Seattle District of the USACE highlight the importance of sustainable water storage solutions in arid regions like Grant County, Washington. As the lagoon continues to support local agriculture and environmental conservation efforts, it stands as a testament to the innovative engineering and regulatory oversight that drive effective water resource management in the Pacific Northwest.

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.
Plan around the weather

About Simplot Lrar Lagoon
Where does the data for Simplot Lrar Lagoon 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 Low 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.
