Mccallum Lake Dam dam
Mccallum Lake Dam
McCallum Lake Dam, located in Denton, Texas, was completed in 1973 and serves multiple purposes including fire protection, stock, small fish pond, recreation, and water supply. This private dam stands at a height of 18 feet with a length of 630 feet, holding a maximum storage of 101 acre-feet and a normal storage capacity of 45 acre-feet. The dam is primarily an earth structure with buttress core types and is regulated by the Texas Commission on Environmental Quality (TCEQ).
Despite its relatively small size, McCallum Lake Dam poses a high risk (2) according to risk assessment data. It lacks a spillway and has no drainage area, presenting challenges in managing potential overflow situations. The dam does not have an emergency action plan in place and is currently not rated for its condition assessment, raising concerns about its structural integrity and overall safety. With the absence of inundation maps and updated emergency contacts, there are key areas for improvement in the risk management measures for this dam.
For water resource and climate enthusiasts, McCallum Lake Dam offers a unique case study in the management and regulation of private dams in Texas. By examining its design, purpose, and risk profile, researchers and policymakers can gain valuable insights into the challenges and opportunities associated with small-scale water infrastructure projects. The dam's high risk designation underscores the importance of implementing comprehensive safety measures and emergency preparedness protocols to mitigate potential hazards and protect surrounding communities and ecosystems.

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 Mccallum Lake Dam
Where does the data for Mccallum Lake 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 Not Available 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.
