Lenth Wetland Dam (Upper Pool) dam
Lenth Wetland Dam (Upper Pool)
Located in Van Buren, Iowa, the Lenth Wetland Dam (Upper Pool) is a state-owned structure with a primary purpose of serving as a Fish and Wildlife Pond. Built in 2000 by the NRCS, this Earth-type dam stands at a height of 9 feet and spans a length of 3675 feet. With a normal storage capacity of 213 acre-feet and a drainage area of 1.09 square miles, the dam provides essential habitat for fish and wildlife in the area.
The dam's low hazard potential and moderate risk assessment make it a valuable asset for water resource and climate enthusiasts. Managed by the Iowa DNR, the Lenth Wetland Dam plays a crucial role in regulating water flow along the TR-FOX RIVER, ultimately benefiting the surrounding ecosystem. Despite not being currently rated for condition assessment, the dam remains a key feature in the region's water management infrastructure, ensuring the conservation of natural resources and enhancing biodiversity.
As part of the Kansas City District, the Lenth Wetland Dam (Upper Pool) stands as a testament to the collaborative efforts between state and federal agencies in promoting sustainable water management practices. With its strategic location near the Mississippi River and its vital role in supporting fish and wildlife populations, this dam serves as a model for effective ecosystem conservation and climate resilience initiatives in the region.

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 Lenth Wetland Dam (Upper Pool)
Where does the data for Lenth Wetland Dam (Upper Pool) 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.
