P16-5 Reservoir dam
P16-5 Reservoir
P16-5 Reservoir, located in Campbell, Wyoming, is a privately owned earth dam completed in 2006 with a primary purpose of irrigation. The reservoir has a maximum storage capacity of 92 acre-feet and a normal storage capacity of 75 acre-feet, serving various needs such as fire protection, stock, and small fish pond in addition to irrigation. With a surface area of 6 acres and a drainage area of 0.06 square miles, the reservoir is fed by Scotty Draw and has a maximum discharge rate of 14 cubic feet per second.
Despite its low hazard potential, P16-5 Reservoir is in poor condition according to a 2017 assessment. The structural height of the dam is 49 feet, with a hydraulic height of 35 feet and a dam height of 40 feet. The reservoir has an uncontrolled spillway type with a width of 2 feet and is equipped with one valve outlet gate. While the reservoir is state-regulated and regularly inspected, there is room for improvement in its maintenance and emergency preparedness, given its moderate risk assessment rating.
Overall, P16-5 Reservoir is a vital water resource for the area, providing essential irrigation water and serving multiple purposes. As a key component of the local water infrastructure, it is important for stakeholders to address the poor condition assessment and ensure that appropriate risk management measures are in place to safeguard the reservoir and surrounding community in case of emergencies.

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 P16-5 Reservoir
Where does the data for P16-5 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.
