About this dam

Layton Reservoir 1

Layton Reservoir 1, located in Crook, Oregon, is a privately owned earth dam that was completed in 1977 for irrigation purposes. With a height of 25 feet and a storage capacity of 177 acre-feet, this reservoir plays a crucial role in water management in the region. The dam controls the flow of Grinstone Creek and has a surface area of 19.4 acres, serving as a vital resource for agricultural activities in the area.

Despite being classified as having a low hazard potential, Layton Reservoir 1 is subject to regular state inspections and enforcement measures to ensure its structural integrity and safety. The reservoir features a slide gate outlet and an uncontrolled spillway type, with a maximum discharge capacity of 898 cubic feet per second. The risk assessment for this dam is moderate, highlighting the importance of ongoing risk management measures to mitigate any potential hazards and ensure the safety of downstream communities.

With its strategic location and significant storage capacity, Layton Reservoir 1 is a key component of the water resource infrastructure in Oregon. As climate change continues to impact water availability and usage patterns, the proper maintenance and monitoring of dams like Layton Reservoir 1 are essential for sustainable water management practices. This reservoir serves as a critical asset for irrigation purposes and underscores the importance of responsible water resource management in the face of changing environmental conditions.

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 Layton Reservoir 1

Where does the data for Layton Reservoir 1 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.
