About this dam

White Trout Water Conservation Structure

White Trout Water Conservation Structure, also known as Hil29, is a state-owned facility located in Hillsborough, Florida, specifically in the city of Tampa. Situated on White Trout Lake, this structure plays a crucial role in flood risk reduction, recreation, and water supply. With a primary purpose of flood risk reduction, White Trout Water Conservation Structure is designed as an earth dam with a height of 17 feet and a length of 334 feet, providing a storage capacity of 4102 acre-feet.

Managed by the Southwest Florida Water Management District (SWFWMD), this structure is state-regulated and subject to regular inspection, enforcement, and permitting. Its spillway type is uncontrolled with a width of 7 feet, and the facility is classified as having a significant hazard potential with a fair condition assessment as of April 2016. While the risk assessment is moderate, White Trout Water Conservation Structure continues to serve its community by safeguarding against flooding, providing recreational opportunities, and ensuring a stable water supply for the area.

As a vital component of water resource management in the region, White Trout Water Conservation Structure exemplifies the intersection of environmental conservation and public safety. With its strategic location and multifaceted purposes, this state-owned facility stands as a testament to the proactive approach taken by Florida authorities in safeguarding their water resources. From flood risk reduction to recreational benefits, White Trout Water Conservation Structure remains a key asset in the sustainable management of water supplies in Hillsborough County.

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 White Trout Water Conservation Structure

Where does the data for White Trout Water Conservation Structure 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.
