Bass Pond dam
Bass Pond
Bass Pond, located in Johnson County, Wyoming, is a privately owned earth dam with a primary purpose of irrigation. Built in 1910, this dam stands at 31 feet high and has a hydraulic height of 26 feet, providing a storage capacity of 271 acre-feet. With a surface area of 23 acres and a drainage area of 4.8 square miles, Bass Pond serves multiple purposes including fire protection, stock watering, and as a small fish pond in addition to irrigation.
The dam's spillway is uncontrolled with a width of 70 feet, and it has a low hazard potential with a satisfactory condition assessment as of June 2019. The last inspection date was in June 2019, indicating a regular inspection frequency of every 5 years. Despite being privately owned, the dam is regulated by the State of Wyoming and has state jurisdiction, permitting, inspection, and enforcement in place to ensure its safety and functionality. Bass Pond is situated along Andrus Draw and serves as an essential water resource for the surrounding area.
Climate and water resource enthusiasts will appreciate the historical significance and multifunctional aspects of Bass Pond, which continues to play a crucial role in irrigation and water management in the region. With moderate risk assessment and a well-maintained condition, this earth dam showcases the importance of proper infrastructure for sustainable water use. Its location in a picturesque setting along Andrus Draw adds to its appeal as a valuable asset in the local ecosystem and agricultural landscape.

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 Bass Pond
Where does the data for Bass Pond 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.
