About this dam

Heritage Point Lake Dam

Heritage Point Lake Dam, also known as Davis Dam, is a private earth dam located in Wayne County, Iowa. Constructed in 1971 by the USDA NRCS, this dam serves multiple purposes including fire protection, stock retention, and small fish pond management. With a height of 47 feet and a length of 900 feet, the dam holds a normal storage capacity of 1203 acre-feet and covers a surface area of 78.9 acres.

Managed by the Iowa Department of Natural Resources, Heritage Point Lake Dam is regulated, inspected, and enforced to ensure its structural integrity and safety. With a significant hazard potential and a satisfactory condition assessment, the dam underwent its last inspection in May 2018. Despite moderate risk levels, the dam is deemed to meet guidelines for emergency action plans, although further risk management measures may be considered to enhance its resilience to potential threats.

Situated on the TR-South Chariton River, Heritage Point Lake Dam plays a crucial role in water resource management in the region. As a focal point for recreation and wildlife habitat, the dam's presence underscores the importance of sustainable dam operations and maintenance to safeguard its surrounding environment and communities. With ongoing oversight and periodic assessments, Heritage Point Lake Dam continues to be a vital asset for water conservation and climate resilience efforts in Iowa.

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 Heritage Point Lake Dam

Where does the data for Heritage Point Lake Dam 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 Significant 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.
