About this dam

Pine Cone No. 1

Pine Cone No. 1, located in Rock River, Wyoming, is a privately owned Earth dam constructed in 1976 for irrigation purposes along the Pine Creek. With a height of 30 feet and a storage capacity of 585 acre-feet, this dam serves the local agricultural community by providing water for irrigation. Despite its low hazard potential, the dam is in poor condition as of the last assessment in 2018, raising concerns about its long-term safety and effectiveness.

Managed by the Sacramento District of the US Army Corps of Engineers, Pine Cone No. 1 has a spillway width of 15 feet and an uncontrolled spillway type. The dam is equipped with a single valve outlet gate for water release. While the dam has not undergone recent modifications, its inspection frequency is set at 5 years to ensure compliance with state regulations and safety standards. With a moderate risk assessment rating of 3, there is a need for proactive risk management measures to address the dam's poor condition and ensure the safety of downstream communities and agricultural lands.

In the event of an emergency, the dam lacks an Emergency Action Plan (EAP) and inundation maps, highlighting the need for improved emergency preparedness. As the dam is located in a low-risk area, efforts to address its poor condition and develop proper risk management strategies are essential to prevent potential hazards and ensure the long-term sustainability of water resources in the region. For water resource and climate enthusiasts, Pine Cone No. 1 serves as a case study in the importance of dam maintenance and emergency preparedness in safeguarding water supplies and protecting communities from potential risks associated with aging 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.

FAQ

About Pine Cone No. 1

Where does the data for Pine Cone No. 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.
