Brown Lake Dam dam
Brown Lake Dam
Brown Lake Dam, located in Forest Green, Missouri, serves the primary purpose of irrigation. Built in 1977, this private Earth dam stands at a height of 12 feet and has a storage capacity of 96 acre-feet. The dam overlooks TR-Sweet Spring Creek and covers a surface area of 15 acres, with a drainage area of 590 square miles. Despite not being state-regulated or inspected, the dam presents a high hazard potential due to its condition being not rated.
With a maximum storage capacity of 96 acre-feet, Brown Lake Dam plays a crucial role in supporting irrigation activities in the region. The dam's buttress core design and unlisted foundation make it a unique structure in the area, contributing to the conservation of water resources for agricultural purposes. While the dam has not been rated for its condition, its high hazard potential underscores the importance of regular inspections and maintenance to ensure the safety of downstream communities and ecosystems.
As an essential component of water resource management in Randolph County, Missouri, Brown Lake Dam requires ongoing risk assessment and management measures to mitigate potential hazards. Despite not being under federal or state jurisdiction, the dam's significance in supporting irrigation activities underscores the need for proactive monitoring and emergency preparedness. Water resource and climate enthusiasts can appreciate the delicate balance between harnessing water for agricultural use and ensuring the safety and sustainability of dams like Brown Lake in the face of changing environmental conditions.

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 Brown Lake Dam
Where does the data for Brown 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.
