About this dam

Limerick Lake Dam

Limerick Lake Dam, located in Mason County, Washington, stands as a pivotal structure regulating the flow of Cranberry Creek. Built in 1966, this private-owned Earth dam serves primarily for recreational purposes, offering a storage capacity of 1600 acre-feet. With a hydraulic height of 34 feet and a structural height of 28 feet, the dam boasts a significant impact on the local watershed, covering a surface area of 130 acres and draining an 11.3 square mile watershed.

Maintained and regulated by the Washington Dept of Ecology, Limerick Lake Dam has undergone regular inspections, with its last assessment conducted in August 2020, deeming its condition satisfactory. Classified as having a high hazard potential, the dam is equipped with emergency action plans to ensure the safety of surrounding communities in case of a breach. Despite its age, the dam's design and construction have stood the test of time, meeting regulatory standards and providing a reliable source of recreation for residents and visitors alike.

As part of Congressional District 06, Washington, Limerick Lake Dam plays a crucial role in managing water resources and mitigating flood risks in the region. With its strategic location and operational efficiency, the dam continues to serve as a vital infrastructure for water management, highlighting the importance of sustainable practices in safeguarding our natural environment amidst changing climate conditions.

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 Limerick Lake Dam

Where does the data for Limerick 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.
