About this dam

Ward Paper Company

The Ward Paper Company, located in Merrill, Wisconsin, is a privately owned facility that plays a crucial role in water supply management in the area. The dam associated with the company serves multiple purposes, including flood risk reduction, hydroelectric power generation, and providing water supply to the local community. Built in 1904, the gravity dam stands at a height of 21 feet and has a storage capacity of 1000 acre-feet.

With a drainage area of 209 square miles and a maximum discharge of 5000 cubic feet per second, the Ward Paper Company dam is designed to withstand high hazard potential events. Despite being rated as "Not Rated" in terms of condition assessment, the facility has a risk assessment of "Very High (1)" and is under state regulation, with inspection, permitting, and enforcement processes in place. The dam has a controlled spillway and a history of modifications dating back to 1905, reflecting a commitment to maintaining its functionality and safety.

Overall, the Ward Paper Company dam is a significant infrastructure for water resource management in Lincoln, Wisconsin. Its strategic location on the Prairie River, coupled with its multiple functions and high hazard potential, highlights the importance of ensuring its continued operation and maintenance to meet the water supply needs of the surrounding community and mitigate potential risks associated with its operation.

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.

FAQ

About Ward Paper Company

Where does the data for Ward Paper Company 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 High 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.
