Louisa Creek dam
Louisa Creek
Louisa Creek is a privately owned water resource located in Owyhee, Idaho, with a dam completed in 1931 for purposes other than irrigation or drinking water supply. The dam is a concrete structure with a multi-arch core type and stands at a height of 41 feet, with a hydraulic height of 38 feet. The reservoir has a storage capacity of 175 acre-feet and covers a surface area of 9 acres, serving a drainage area of 8.2 square miles.
Despite its low hazard potential, Louisa Creek's dam is currently in poor condition, with a risk assessment rating of moderate. The last inspection in June 2019 highlighted the need for improvement, with an inspection frequency of 4 years. The dam features an uncontrolled spillway with a width of 3 feet and a maximum discharge of 30 cubic feet per second. While the risk management measures and emergency action plan status are unknown, the dam's location and structural specifications make it a valuable resource for water resource and climate enthusiasts interested in Idaho's hydrological infrastructure.
Overall, Louisa Creek represents a historic and functional water resource in Idaho, standing as a testament to early 20th-century engineering and serving as a vital component of the local watershed. With its unique design and operational characteristics, the dam provides a fascinating glimpse into the intersection of human intervention and natural water systems, making it a point of interest for those interested in water resource management and climate resilience in the region.

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 Louisa Creek
Where does the data for Louisa Creek 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.
