Zoglmann Reservoir dam
Zoglmann Reservoir
Zoglmann Reservoir, located in Harney County, Oregon, is a privately owned earth dam constructed in 1963 primarily for irrigation purposes. The reservoir has a maximum storage capacity of 3000 acre-feet and a normal storage capacity of 2533 acre-feet, serving the agricultural needs of the region. Situated in the Gumboot Canyon along the Gumboot Creek, the reservoir covers an area of 228.8 acres and has a drainage area of 25.3 square miles.
With a dam height of 27.7 feet and a hydraulic height of 23 feet, Zoglmann Reservoir is considered to have a low hazard potential. The dam features outlet gates in the form of slide (sluice gate) mechanisms for controlled water release. The last inspection of the reservoir took place in July 2009, with a scheduled inspection frequency of 6 years. While the condition assessment of the dam is listed as "Not Rated," the reservoir is under state regulation and inspection by the Oregon Water Resources Department (OWRD), ensuring compliance with safety standards and enforcement measures.
Water resource and climate enthusiasts can appreciate Zoglmann Reservoir for its role in sustaining agricultural activities in the region and its contribution to water management in the Gumboot Canyon area. The reservoir's strategic location and design highlight the importance of efficient irrigation infrastructure in optimizing water resources for sustainable development. As a key component of the local water supply system, Zoglmann Reservoir showcases the intersection of human intervention and natural hydrological processes in maintaining water security for the community.

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 Zoglmann Reservoir
Where does the data for Zoglmann Reservoir 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.
