Morrison Onan Farm Dam dam
Morrison Onan Farm Dam
Morrison Onan Farm Dam, also known as Onan Farm Lake, is a private-owned water resource located in the Rineltown area of Washington County, Kentucky. Built in 1967 by the Soil Conservation Service, this Earth-type dam stands at 26 feet tall and spans a length of 424 feet, with a storage capacity of 56 acre-feet for irrigation purposes. The dam is regulated by the Kentucky Division of Water and has a low hazard potential, with a moderate risk assessment rating.
The dam is situated on Mill Creek offstream and serves as a crucial water source for the surrounding agricultural lands. Despite its age, the condition of the dam is not rated, and it has not been inspected since 2004. The dam features an uncontrolled spillway type, and while it meets state regulatory standards, there are no emergency action plans in place. With a drainage area of 0.06 square miles and a normal storage capacity of 37 acre-feet, the Morrison Onan Farm Dam plays a vital role in sustaining local water resources for irrigation purposes in the region.
As a key structure in the water management system of Kentucky, the Morrison Onan Farm Dam represents a blend of historical significance and practical utility. Although it has not undergone recent inspections or condition assessments, the dam continues to provide essential irrigation water to the agricultural community in the Rineltown area. With its moderate risk assessment rating and low hazard potential, the dam stands as a testament to the importance of maintaining and monitoring water resources to ensure their safety and sustainability for future generations.

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 Morrison Onan Farm Dam
Where does the data for Morrison Onan Farm 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 Low 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.
