Mravik dam
Mravik
Mravik, also known as Pershing Wildlife Area, is a state-owned structure located in Taylor, Wisconsin. This dam, designed by the USDA NRCS and completed in 1967, serves a primary purpose beyond traditional water resource management. The Earth-type dam stands at 11 feet high and spans 710 feet in length, with a storage capacity of 160 acre-feet.
Situated on the Trib Fisher River, Mravik plays a crucial role in managing water flow and enhancing conservation efforts in the region. Despite its low hazard potential and fair condition assessment, the structure is subject to regular state inspections, permitting, and enforcement by the Wisconsin Department of Natural Resources. The dam's controlled spillway, with a width of 68 feet, ensures efficient water discharge during peak flow events, contributing to the overall safety and resilience of the surrounding area.
With a risk assessment rating of 'Very High (1)', Mravik underscores the importance of proactive risk management measures and emergency preparedness. While the structure has not been modified in recent years, its critical role in water storage, flood control, and habitat preservation highlights the intersection of water resource management and climate resilience in a changing environment. As enthusiasts in the field of water resources and climate, understanding the significance of structures like Mravik is essential for promoting sustainable practices and safeguarding our natural ecosystems for future generations.
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 Mravik
Where does the data for Mravik 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.
