Clark County 1 dam
Clark County 1
Clark County 1, located in Clark County, Wisconsin, is a gravity-type dam completed in 1934 for recreational purposes on the Fivemile Creek. The dam stands at a height of 7 feet with a hydraulic height of 4.3 feet and a length of 36 feet. It has a storage capacity of 120 acre-feet and a drainage area of 3.4 square miles, with a maximum discharge of 322 cubic feet per second. Despite being rated as having a low hazard potential, the dam is deemed to have a very high risk due to its condition assessment being not rated.
This dam is under the jurisdiction of the Wisconsin Department of Natural Resources (WIDNR), which regulates, permits, inspects, and enforces standards for its operation. The last inspection of Clark County 1 was conducted in September 2009, with a scheduled inspection frequency of 10 years. While the dam has not been assessed for its condition recently, it is crucial for water resource and climate enthusiasts to monitor its risk level and management measures in light of its potential impact on the surrounding area in the event of an emergency.
With its controlled spillway and surface area of 14 acres, Clark County 1 serves as a crucial recreational structure in the region. As a part of the Detroit District and Congressional District 07 of Wisconsin, this dam plays a significant role in providing recreational opportunities while also posing potential risks that should be carefully managed and monitored by relevant authorities and stakeholders in the water resource and climate community.

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 Clark County 1
Where does the data for Clark County 1 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.
