Desiltation Project 73-2 dam
Desiltation Project 73-2
Desiltation Project 73-2, located in Nobles County, Minnesota, is a gravity dam constructed in 1977 with a primary purpose of other water resource management. Managed by NRCS and owned by the local government, this project plays a vital role in regulating the flow of Jack Creek-TR and protecting the surrounding area from potential flooding. With a dam height of 8 feet and a length of 500 feet, the structure has a normal storage capacity of 25 acre-feet and a maximum storage of 60 acre-feet, serving a drainage area of 8.6 square miles.
Although classified as having a low hazard potential and being in satisfactory condition, Desiltation Project 73-2 undergoes inspections every 8 years to ensure its continued safety and effectiveness. The last assessment in 2018 confirmed its overall structural integrity, but continuous monitoring and maintenance are essential to prevent any potential risks or failures. With state regulation and enforcement in place, this dam is a crucial component of the local water resource infrastructure, serving as a reliable tool for flood control and water management in the region.
As water resource and climate enthusiasts, the significance of Desiltation Project 73-2 lies in its role as a key player in sustainable water management practices. With a focus on desiltation and sediment control, this project not only ensures the efficient operation of the dam but also contributes to the overall health of the ecosystem and water quality in the area. By adhering to state regulations and inspection protocols, this gravity dam remains a valuable asset in safeguarding the community and environment against potential water-related challenges.

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 Desiltation Project 73-2
Where does the data for Desiltation Project 73-2 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 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.
