Wenatchee Heights Reservoir No 2 Dam dam
Wenatchee Heights Reservoir No 2 Dam
The Wenatchee Heights Reservoir No 2 Dam is a crucial water resource infrastructure in Malaga, Washington, completed in 1998 with a primary purpose of recreation. Owned by a public utility, it is regulated by the Washington Dept of Ecology and is subject to state inspection and enforcement. The dam, standing at a hydraulic height of 25 feet and a structural height of 28 feet, has a storage capacity of 94 acre-feet and serves irrigation and recreation purposes, while being built primarily with earth and stone materials on a soil foundation.
Located on Orr Creek-Offstream, this dam plays a vital role in water management in Chelan County, Washington, serving a drainage area of 0.02 square miles. Despite having a fair condition assessment, the dam has a high hazard potential, prompting a five-year inspection frequency to ensure its safety and integrity. With its capacity to store up to 94 acre-feet of water and cover a surface area of 2.7 acres, the Wenatchee Heights Reservoir No 2 Dam is a significant asset for water resource and climate enthusiasts in the region.
Managed by a public utility and regulated by the state, the Wenatchee Heights Reservoir No 2 Dam stands as a critical infrastructure for irrigation and recreation in Chelan County. With its strategic location in Malaga, Washington, and a storage capacity of 94 acre-feet, this dam serves as a key component in water management and resource allocation in the region. Despite its fair condition assessment and high hazard potential, regular inspections and maintenance ensure its continued functionality for the benefit of water resource and climate enthusiasts in the area.
Dam data reference
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 Wenatchee Heights Reservoir No 2 Dam
Where does the data for Wenatchee Heights Reservoir No 2 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.
