Lacamas & Round Lakes Lower Dam dam
Lacamas & Round Lakes Lower Dam
Lacamas & Round Lakes Lower Dam, located in Camas, Washington, is a buttress dam constructed in 1936 primarily for water supply purposes. The dam stands at a hydraulic height of 26 feet and has a storage capacity of 6,800 acre-feet, with a normal storage level of 6,100 acre-feet. Lacamas & Round Lakes Lower Dam plays a crucial role in providing water to the surrounding area and also offers recreational opportunities for the community.
Managed by the local government and regulated by the Washington Department of Ecology, the dam has a low hazard potential and is in satisfactory condition as of the last assessment in April 2018. The structure spans Lacamas Creek and covers a drainage area of 64.7 square miles. Although the dam has not been modified in recent years, it undergoes regular inspections to ensure its safety and functionality, with the last inspection conducted in September 2017.
With its picturesque location and vital role in water supply management, Lacamas & Round Lakes Lower Dam serves as a significant landmark in the region. Visitors can enjoy the scenic beauty of the surrounding area while appreciating the engineering marvel that is the multi-arch buttress dam. As climate change continues to impact water resources, the preservation and maintenance of dams like Lacamas & Round Lakes Lower Dam are crucial in ensuring water security for both current and future generations.
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 Lacamas & Round Lakes Lower Dam
Where does the data for Lacamas & Round Lakes Lower 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 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.
