Meacham Lake Dam dam
Meacham Lake Dam
Meacham Lake Dam, also known as Beaver Creek Dam, is a privately owned structure located in Umatilla, Oregon. This earth dam sits on Beaver Creek, a tributary of Meacham Creek, with a dam height of 14 feet and a storage capacity of 160 acre-feet. The dam is designed by KRUMBEIN and is regulated by the Oregon Water Resources Department, with state permitting, inspection, and enforcement in place.
With a significant hazard potential and a moderate risk assessment rating of 3, Meacham Lake Dam plays a crucial role in water resource management in the region. The dam has an uncontrolled spillway and is equipped with slide gates for outlet control. Although the dam's condition assessment is currently rated as "Not Rated," regular inspections are conducted, with the last inspection taking place in December 2020. The dam's emergency action plan status and risk management measures are not provided in the data.
Water resource and climate enthusiasts interested in the operational details and risk factors associated with Meacham Lake Dam would find this information valuable. The dam's location, design characteristics, and regulatory oversight highlight its importance in flood control and water storage for the surrounding area. Further assessment of the dam's condition and emergency preparedness measures would be beneficial for ensuring the safety and sustainability of this 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.

About Meacham Lake Dam
Where does the data for Meacham 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 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.
