Samaria No 1 Lower dam
Samaria No 1 Lower
Samaria No 1 Lower, also known as Pleasantview Lower, is a privately owned dam located in Oneida, Idaho. Completed in 1934, this earthen dam stands at a height of 35.1 feet and has a hydraulic height of 29.6 feet. With a storage capacity of 559 acre-feet and a drainage area of 7.1 square miles, this dam plays a crucial role in managing water resources in the region.
Situated on the Malad River and Bear River, Samaria No 1 Lower has a spillway width of 13 feet and a maximum discharge capacity of 144 cubic feet per second. The dam's hazard potential is considered significant, but its condition assessment as of May 2017 was rated as fair. While the risk assessment for this dam is moderate, there are no specific risk management measures outlined for its operation.
Despite being privately owned, Samaria No 1 Lower falls under state regulation by the Idaho Department of Water Resources, with permitting, inspection, and enforcement processes in place. This dam not only serves as a vital infrastructure for water management but also poses challenges in terms of its hazard potential and risk assessment, highlighting the importance of ongoing monitoring and maintenance for water resource and climate enthusiasts in the area.
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 Samaria No 1 Lower
Where does the data for Samaria No 1 Lower 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.
