Summary
Johns, Florida, is a state-regulated dam with a primary purpose of flood risk reduction. This earth dam, with a height of 10 feet and a hydraulic height of 8 feet, was completed with a storage capacity of 152 acre-feet and a normal storage of 102 acre-feet. The dam spans a length of 5495 feet and sits on a drainage area of 0.02 square miles, serving as a critical infrastructure in managing water resources in the region.
Despite being classified as having a low hazard potential, Deep Creek West was assessed to be in fair condition as of May 2017. The dam is monitored and maintained by the St. Johns River Water Management District, with state jurisdiction and permitting in place. While primarily designed for flood risk reduction, the dam also supports recreation and water supply purposes in the area. Its location along the Deep Creek tributary and proximity to the city of Hastings highlight its importance in safeguarding against potential water-related hazards and ensuring the sustainable management of water resources.
With a risk assessment deemed moderate, efforts are in place to continually evaluate and manage any potential risks associated with Deep Creek West. Emergency action plans and risk management measures are integral components in ensuring the safety and functionality of the dam. As water resource and climate enthusiasts, staying informed about the condition and maintenance of critical infrastructure like Deep Creek West is vital in promoting resilience and sustainability in the face of changing environmental conditions.

Condition Assessment
SatisfactoryNo 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. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
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. Investigations and studies are necessary.
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.
Not Available
Dams for which the condition assessment is restricted to approved government users.
Hazard Potential Classification
HighDams 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, environment 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.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
