J. J. Huddart No. 1 dam
J. J. Huddart No. 1
J. J. Huddart No. 1, also known as Hanks or Lacamora, is a local government-owned irrigation dam located in Lafayette, Colorado. Built in 1962 by the USDA NRCS, this earth dam stands at a height of 20 feet with a hydraulic height of 25 feet, serving the primary purpose of irrigation. With a storage capacity of 42 acre-feet and a maximum discharge of 150 cubic feet per second, this dam plays a vital role in managing water resources in the region.
Situated on Rock Creek in Broomfield County, J. J. Huddart No. 1 is regulated by the Colorado Department of Water Resources (DWR) and is under state jurisdiction for permitting, inspection, and enforcement. Despite being rated as low hazard potential and not yet assessed for condition, this dam presents a moderate risk (3 out of 5) due to its age and design characteristics. While it does not have an emergency action plan or inundation maps prepared, the dam meets regulatory guidelines and is equipped with an uncontrolled spillway to manage excess water flow.
Although not owned or funded by federal agencies, J. J. Huddart No. 1 is an essential water infrastructure managed by local authorities for agricultural irrigation purposes. With its strategic location and operational history since the 1960s, this dam continues to contribute to the sustainable management of water resources in the area, ensuring a reliable water supply for the surrounding community.
Dam data reference
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 J. J. Huddart No. 1
Where does the data for J. J. Huddart 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 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.
