Raintree Dam #2 dam
Raintree Dam #2
Located in Hillsboro, Missouri, Raintree Dam #2 is a privately owned recreational dam completed in 1989. Designed by SHANNON, WILSON, this Earth-type dam stands at a structural height of 55 feet and spans 1000 feet in length, holding a maximum storage capacity of 988 acre-feet of water. Situated on the BELEW CREEK TRIBUTARY, the dam serves as a popular spot for outdoor activities such as fishing, boating, and picnicking, offering a serene escape for water resource and climate enthusiasts.
Despite its satisfying condition assessment, Raintree Dam #2 presents a high hazard potential, requiring regular inspections and enforcement to ensure safety. The dam features an uncontrolled spillway with a width of 17 feet, capable of discharging up to 5582 cubic feet per second during peak flows. With a drainage area of 653 square miles, the dam plays a crucial role in managing water resources in the region and mitigating flood risks along the BELEW CREEK TRIBUTARY, attracting visitors with its scenic beauty and recreational opportunities.
As a key component of the DAM AND RESERVOIR SAFETY PROGRAM in Missouri, Raintree Dam #2 is subject to state regulations and permitting, with inspections conducted every two years to maintain its satisfactory condition. Despite moderate risk assessment, the dam continues to provide valuable benefits to the community, serving as a vital infrastructure for water storage, recreation, and environmental conservation. With its strategic location and well-maintained facilities, Raintree Dam #2 stands as a testament to the importance of responsible water resource management and climate resilience 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 Raintree Dam #2
Where does the data for Raintree Dam #2 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.
