About this dam

Walters

Walters, Glenn #5 is a privately owned earth dam located in Blooming, Oregon, along the Tualatin River. Completed in 1984 for the primary purpose of irrigation, this dam stands at a height of 29 feet and has a storage capacity of 102 acre-feet. With a surface area of 10.7 acres and a drainage area of 0.23 square miles, Walters, Glenn #5 plays a crucial role in supporting agricultural activities in the region.

Managed by the Oregon Water Resources Department, this dam is rated as having a significant hazard potential. The dam features a slide (sluice gate) for outlet gates and has a maximum discharge capacity of 152 cubic feet per second. While the condition assessment is currently not rated, the last inspection was conducted in February 2017 and the dam is subject to regular inspections every three years to ensure its safety and integrity.

For water resource and climate enthusiasts, Walters, Glenn #5 serves as a noteworthy example of how privately owned dams contribute to irrigation infrastructure in the Pacific Northwest. Its location along the Tualatin River tributary highlights the interconnectedness of water resources in the region, while its construction and maintenance by private entities underscore the importance of effective regulatory oversight to ensure the safety and sustainability of such critical infrastructure.

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 Walters

Where does the data for Walters 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 Significant 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.
