Merrick Howard County Road Dam dam
Merrick Howard County Road Dam
Merrick Howard County Road Dam in Nebraska, managed by the local government, was designed by the USDA NRCS and stands as a crucial structure for flood risk reduction along TR-ROCK CREEK. Completed in 1980, this earth dam rises 41 feet high and spans 600 feet in length, providing a maximum storage capacity of 173 acre-feet. Despite its low hazard potential, the dam's condition was rated as poor during the last inspection in May 2018.
Located in Fullerton, Nebraska, this dam plays a vital role in safeguarding the surrounding area from potential flooding events. The Nebraska Department of Natural Resources oversees state regulation, permitting, inspection, and enforcement related to the dam's operations. With a drainage area of 0.9 square miles and a normal storage capacity of 38 acre-feet, the dam's hydraulic height of 33 feet ensures effective flood risk mitigation for the community.
Given its critical purpose and historical significance, the Merrick Howard County Road Dam symbolizes the collaborative efforts between local and federal agencies in managing water resources and climate-related challenges. Despite its poor condition assessment, ongoing inspections and enforcement measures by the NE DNR aim to maintain the dam's integrity and functionality 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 Merrick Howard County Road Dam
Where does the data for Merrick Howard County Road 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.
