About this dam

Hickory Brch Dm2

Hickory Branch Dam 2, located in Highlands County, Florida, is a privately owned earth dam designed by the USDA NRCS and completed in 1961 for irrigation purposes. With a height of 21 feet and a length of 350 feet, the dam has a storage capacity of 345 acre-feet and serves a drainage area of 2.5 square miles. Despite its low hazard potential, the dam's condition has not been recently assessed, with the last inspection dating back to 1994.

The dam's primary purpose of irrigation underscores its crucial role in water resource management in the Placid Lakes area. While the dam currently meets regulatory standards for permitting, inspection, and enforcement, its emergency action plan and risk assessment measures are lacking. Given its location on the Hickory Branch stream, a comprehensive risk management strategy and regular condition assessments could enhance the dam's resilience to climate change impacts and ensure the safety of downstream communities.

As water resource and climate enthusiasts monitor the evolving landscape of dam safety and resilience, Hickory Branch Dam 2 presents an opportunity for proactive risk mitigation and emergency preparedness efforts. With its historic significance and strategic importance for irrigation in the region, stakeholders may consider enhancing the dam's regulatory compliance, conducting regular inspections, and developing a comprehensive emergency action plan to safeguard water resources and mitigate potential risks associated with extreme weather events.

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 Hickory Brch Dm2

Where does the data for Hickory Brch Dm2 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.
