Sand Dunes Wastewater Lagoon Dam dam
Sand Dunes Wastewater Lagoon Dam
The Sand Dunes Wastewater Lagoon Dam in Morrow, Oregon, is a significant component of the local infrastructure, owned and regulated by the local government. This dam, with a height of 34.5 feet and a storage capacity of 1264 acre-feet, plays a crucial role in wastewater management in the area. While specific details regarding its design and construction are unavailable, its state-regulated status ensures that it meets necessary safety and environmental standards.
The dam's hazard potential is categorized as significant, highlighting the importance of regular inspections and maintenance to ensure its structural integrity. Despite being not rated in terms of condition assessment, its emergency action plan readiness and risk management measures are key aspects to monitor. Located within the purview of multiple USACE districts, including Portland, Seattle, and Walla Walla, this dam serves as a key water resource in the region and requires ongoing attention to mitigate potential risks and ensure its continued functionality for the community.
Water resource and climate enthusiasts interested in the Sand Dunes Wastewater Lagoon Dam can appreciate its role in local wastewater management and its contribution to the overall water infrastructure in Morrow, Oregon. With a significant hazard potential and a sizable storage capacity, this dam requires consistent monitoring and adherence to regulatory standards to safeguard against potential risks. As a locally owned and state-regulated structure, it underscores the importance of effective emergency preparedness and risk management strategies to ensure its long-term viability and reliability in serving the community's water needs.

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 Sand Dunes Wastewater Lagoon Dam
Where does the data for Sand Dunes Wastewater Lagoon 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 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.
