About this dam

Carlisle Lake Dam

Carlisle Lake Dam, located in Lewis, Washington, serves as a vital structure for fish and wildlife conservation, as well as recreational activities. Built in 1920 with an earth core and stone foundation, this dam stands at 19 feet high and has a storage capacity of 300 acre-feet for the South Fork Newaukum River. Despite being privately owned, the Washington Department of Ecology regulates and inspects this dam to ensure its safety and compliance with state laws.

With a surface area of 29 acres and a drainage area of 4.15 square miles, Carlisle Lake Dam plays a crucial role in maintaining the surrounding ecosystem and providing water resources for various purposes. The dam's hazard potential is deemed high, but its fair condition assessment in 2016 indicates ongoing efforts to ensure public safety. Although no spillway type or outlet gates are specified, the dam's emergency action plan status and risk assessment remain unclear, highlighting the need for updated emergency protocols and risk management measures.

As climate change continues to impact water resources and infrastructure, staying informed about the condition and management of dams like Carlisle Lake Dam is essential for water resource and climate enthusiasts. By understanding the dam's design, purpose, and regulatory oversight, stakeholders can work together to ensure the safety and sustainability of this vital water management structure in Washington.

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.

FAQ

About Carlisle Lake Dam

Where does the data for Carlisle Lake 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 High 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.
