About this dam

Goshen No. 1

Goshen No. 1, also known as Bump-Sullivan See 4020r, is a privately owned irrigation dam located in Goshen County, Wyoming. Completed in 1924, this Earth-type dam stands at 17 feet high and spans a length of 2160 feet, providing crucial water storage for agricultural purposes in the region. Situated on Horse Creek near Morrill, Nebraska, this dam has a normal storage capacity of 1929 acre-feet and a drainage area of 9.4 square miles.

Despite its historical significance and vital role in irrigation, Goshen No. 1 is currently in poor condition according to a 2019 assessment, with a significant hazard potential. The dam features a single valve outlet gate and an uncontrolled spillway with a width of 30 feet. The inspection frequency for this dam is set at 5 years, highlighting the need for regular maintenance and upkeep to ensure its continued reliability and safety. With a moderate risk rating, there is a call for enhanced risk management measures to address potential safety concerns and mitigate any future hazards that may arise.

As a focal point for water resource and climate enthusiasts, Goshen No. 1 serves as a reminder of the importance of maintaining aging infrastructure to safeguard water supplies and protect surrounding communities from the impacts of dam failure. With its rich history and critical role in supporting agricultural activities, this dam stands as a testament to the intricate balance between human intervention and natural resources in the face of changing environmental conditions. Efforts to address the poor condition of Goshen No. 1 and implement necessary risk management measures will be crucial in ensuring the continued functionality and safety of this vital water resource infrastructure.

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.

FAQ

About Goshen No. 1

Where does the data for Goshen No. 1 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 Significant 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.
