Penrhos Farms #5 dam
Penrhos Farms #5
Penrhos Farms #5 is a privately owned earth dam located in Marshall, South Dakota, along the tributary of Wild Rice Creek. Built in 1976, this dam stands at a height of 14 feet and has a storage capacity of 160 acre-feet. With a low hazard potential and a condition assessment of "Not Rated," Penrhos Farms #5 is regulated by the South Dakota Department of Environment and Natural Resources (DENR) for permitting, inspection, and enforcement.
Situated within the St. Paul District of the US Army Corps of Engineers, Penrhos Farms #5 plays a crucial role in water resource management in the region. The dam's primary purpose and specific associated structures are not specified, but its normal storage capacity of 80 acre-feet and maximum discharge of 3120 cfs highlight its significance in flood control and water supply management. With Dusty Johnson (R) as the Congressional Representative for this area, the dam's operation and maintenance are overseen by the private owner while adhering to state regulatory guidelines.
Overall, Penrhos Farms #5 serves as a vital infrastructure for water resource management in Marshall, South Dakota, contributing to the protection of downstream communities from potential flooding events. While its condition assessment is currently "Not Rated," ongoing inspections and regulatory oversight by the DENR ensure the dam's continued safety and functionality. As a key piece of the water infrastructure in the region, Penrhos Farms #5 underscores the importance of sustainable water resource management practices for climate enthusiasts and stakeholders alike.
Dam data reference
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 Penrhos Farms #5
Where does the data for Penrhos Farms #5 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.
