About this dam

Lake Haven Dam

Lake Haven Dam, located in Henry County, Indiana, was completed in 1954 and serves as a recreational spot for water resource and climate enthusiasts. The dam, standing at a height of 31 feet and stretching 244 feet in length, holds a maximum storage capacity of 155 acre-feet and covers a surface area of 9.8 acres. It is situated on an unnamed tributary of the Big Blue River and is regulated by the Indiana Department of Natural Resources, ensuring state oversight for permitting, inspection, and enforcement.

Despite its primary purpose of recreation, Lake Haven Dam poses a high hazard potential with a poor condition assessment, indicating the need for maintenance and potential risk management measures. The dam's spillway type is uncontrolled with a width of 30 feet, and it features a slide (sluice gate) outlet gate for water release. While the dam has not been modified in recent years, its last inspection in 2018 revealed areas of concern, prompting a moderate risk assessment rating of 3 on a scale of 1 to 5.

For water resource and climate enthusiasts seeking a captivating site to explore, Lake Haven Dam offers a mix of recreational opportunities and a glimpse into the importance of proper dam maintenance and risk management in safeguarding water resources. With its historical significance and picturesque setting, this dam serves as a reminder of the delicate balance between human enjoyment of natural resources and the need for responsible stewardship to ensure safety and sustainability for future generations.

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 Lake Haven Dam

Where does the data for Lake Haven 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 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.

Premium feature
