Powell Sewage Lagoon System-Secondary C4 dam
Powell Sewage Lagoon System-Secondary C4
The Powell Sewage Lagoon System-Secondary C4 in Wyoming is a crucial water resource infrastructure designed by Donald J. Livingston and completed in 1988. This lagoon system is regulated by the State of Wyoming, ensuring that it meets all necessary standards for water quality and environmental protection. With a low hazard potential and fair condition assessment, this system plays a vital role in managing wastewater in the area.
Situated in Park County, Wyoming, the Powell Sewage Lagoon System-Secondary C4 is designed as an earth dam with a height of 11 feet and a hydraulic height of 8 feet. This system has a normal storage capacity of 71 acre-feet, serving its primary purpose of wastewater management effectively. With controlled outlet gates and a surface area of 80 acres, this lagoon system is a key component of the drainage system for Bitter Creek.
Despite being at a high risk level, the Powell Sewage Lagoon System-Secondary C4 is well-maintained and regularly inspected to ensure its continued functionality. With a dedicated emergency action plan in place and updated contact information, this system is equipped to handle any potential risks or emergencies. As a critical piece of water resource infrastructure in the region, the Powell Sewage Lagoon System-Secondary C4 plays a vital role in managing wastewater and protecting the environment.
Plan around the weather
Same NOAA / yr.no feed Snoflo's iOS app uses. Watch the precipitation column on the meteogram -- rain on the basin upstream typically lifts inflow 24-72 hours later.

About Powell Sewage Lagoon System-Secondary C4
Where does the data for Powell Sewage Lagoon System-Secondary C4 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 below 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.

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.
