About this dam

Csr Associated Avenue Retention Dam

Csr Associated Avenue Retention Dam is a vital flood risk reduction infrastructure located in Snohomish, Washington. Designed by Reid Middleton and completed in 2003, this private-owned earth dam stands at a structural height of 30 feet with a hydraulic height of 30 feet, offering protection against potential flooding events along the Tr-Merrill Creek. With a storage capacity of 34 acre-feet, the dam plays a crucial role in managing water resources and mitigating flood hazards in the region.

Managed by the Washington Dept of Ecology, the Csr Associated Avenue Retention Dam has been deemed to have a low hazard potential and is currently rated as "Not Rated" in terms of its condition assessment. With a primary purpose of flood risk reduction, the dam serves as a key component in the overall water resource management strategy for the area. Despite having no associated structures and a limited drainage area, the dam's strategic location and design contribute to its effectiveness in safeguarding the surrounding communities from potential flood incidents.

As an essential piece of infrastructure for water resource and climate enthusiasts, the Csr Associated Avenue Retention Dam stands as a testament to the importance of proactive flood risk reduction measures in safeguarding communities and preserving environmental integrity. With its state-regulated status and adherence to inspection, enforcement, and permitting protocols, the dam represents a model for sustainable water resource management practices in the face of 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 Csr Associated Avenue Retention Dam

Where does the data for Csr Associated Avenue Retention 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.
