Hewlett Lake Dam dam
Hewlett Lake Dam
Hewlett Lake Dam, located in Poplar Bluff, Missouri, is a privately owned structure primarily used for recreation. Built in 1967, this earth dam stands at a height of 25 feet and has a storage capacity of 40 acre-feet. Set on TR-PIKE CREEK, the dam covers a surface area of 3 acres and drains an area of 35 square miles. Despite being categorized as high hazard potential, the dam's condition remains unrated with no recent inspections reported.
The dam, designed as an earth buttress structure, serves as a popular spot for outdoor enthusiasts and nature lovers in the Butler County area. With a maximum storage capacity of 40 acre-feet, Hewlett Lake Dam provides a tranquil setting for recreational activities and wildlife habitat. While the dam has not been regulated or inspected by state agencies, its location in a picturesque setting on TR-PIKE CREEK makes it an appealing destination for visitors seeking relaxation and enjoyment of the natural surroundings.
Although lacking recent assessments and emergency preparedness plans, Hewlett Lake Dam remains a significant feature in the landscape of Poplar Bluff, offering opportunities for outdoor recreation and water-based activities. As water resource and climate enthusiasts, the unique design and purpose of this privately owned dam on TR-PIKE CREEK in Missouri provide an intriguing case study of how man-made structures can harmoniously blend with nature to create a sustainable environment for both humans and wildlife.

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 Hewlett Lake Dam
Where does the data for Hewlett Lake 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.
