Dennis Gisvold dam
Dennis Gisvold
Dennis Gisvold is a privately-owned earth dam located in Taylor, Wisconsin, along the Tr South Fork Yellow River. Designed by the USDA NRCS and completed in 1965, this recreational dam stands at a height of 12 feet with a length of 550 feet, providing storage of 100 acre-feet of water. With a low hazard potential and a moderate risk assessment rating of 3, this structure is currently in good condition with a 10-year inspection frequency.
Managed by the Natural Resources Conservation Service, Dennis Gisvold serves primarily for recreational purposes and is equipped with an uncontrolled spillway and outlet gates. While the dam itself has not undergone modifications in recent years, it remains a key feature in the local water resource management system. The dam's location within the Detroit District under the ownership of private individuals highlights its importance in flood control and water conservation efforts in the area.
Overall, Dennis Gisvold serves as a vital component in the water infrastructure of Taylor, Wisconsin, contributing to the overall water management and recreational activities in the region. Its design and construction by the USDA NRCS reflect a commitment to sustainable water resource practices, while its low hazard potential and moderate risk assessment underline the importance of regular maintenance and inspection to ensure its continued safety and efficiency. As a significant earth dam structure, Dennis Gisvold plays a crucial role in supporting the local ecosystem and enhancing water resilience in the face of changing climate conditions.

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 Dennis Gisvold
Where does the data for Dennis Gisvold 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.
