L.P.Hill Dam #3 dam
L.P.Hill Dam #3
L.P.Hill Dam #3, located in Lake City, Florida, was completed in 1954 by the USDA NRCS and is primarily used for irrigation purposes. This earth dam stands at a height of 21 feet and has a length of 300 feet, with a storage capacity of 74 acre-feet. The dam sits on the TR-Alligator Lake river and is regulated by the state of Florida, with inspections and enforcement measures in place to ensure its safety and functionality.
Despite its high hazard potential and unsatisfactory condition assessment in 2014, L.P.Hill Dam #3 continues to provide vital water resources for irrigation and fish and wildlife ponds in the area. The dam has a spillway width of 65 feet and an uncontrolled spillway type, with a maximum discharge of 130 cubic feet per second. While the risk assessment for the dam is moderate, there are no documented emergency action plans or inundation maps prepared, highlighting the need for continued monitoring and risk management measures to protect the surrounding community and environment.
As a key piece of infrastructure in Columbia County, Florida, L.P.Hill Dam #3 serves as a critical resource for water management and conservation efforts in the region. With its close proximity to Alligator Lake and the surrounding drainage area, the dam plays a crucial role in maintaining water levels for irrigation and wildlife habitats. As water resource and climate enthusiasts, it is important to stay informed about the condition and regulatory oversight of dams like L.P.Hill Dam #3 to ensure the sustainable use of water resources in our community.
Dam data reference
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 L.P.Hill Dam #3
Where does the data for L.P.Hill Dam #3 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.
