Crumly Dam dam
Crumly Dam
Crumly Dam, located in Muscatine, Iowa, is a privately-owned structure designed by the USDA NRCS and completed in 1977. The dam serves multiple purposes, including fire protection and providing a small fish pond for the local community. With a height of 34 feet and a length of 290 feet, Crumly Dam has a storage capacity of 152 acre-feet and covers a surface area of 9.9 acres. The dam is regulated by the Iowa DNR and is inspected regularly to ensure its safety and compliance with state regulations.
Situated in Wild Cat Den State Park along the TR-East Branch Pine Creek, Crumly Dam plays a vital role in water resource management in the area. Despite being classified as having a low hazard potential, the dam is considered to have a moderate risk level, with a risk assessment rating of 3. While the dam is currently in a "Not Rated" condition according to the latest assessment, it is important for stakeholders to continue monitoring and implementing risk management measures to ensure the safety and functionality of the structure for both water resource and climate enthusiasts in the region.
Overall, Crumly Dam stands as a significant infrastructure for the local community, providing essential services such as fire protection and a recreational fish pond. Its construction and maintenance are overseen by the Iowa DNR, with regular inspections to guarantee its structural integrity and compliance with state regulations. As a key component of water resource management in the area, Crumly Dam plays a crucial role in ensuring the safety and sustainability of the surrounding environment for residents and enthusiasts alike.

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 Crumly Dam
Where does the data for Crumly 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.
