Monroe Lake Dam dam
Monroe Lake Dam
Monroe Lake Dam, located in Collin, Texas, was completed in 1961 by the USDA NRCS and serves as a crucial water resource for fire protection, stock, and recreational purposes. Standing at a height of 15 feet with a length of 522 feet, the earth dam is designed with buttress core types and supports the Muddy Creek. Despite its primary purpose for water management, the dam currently lacks a spillway and is not rated for condition assessment.
Owned privately, Monroe Lake Dam falls under the regulatory jurisdiction of the Texas Commission on Environmental Quality (TCEQ) and undergoes regular state inspections and enforcement. With a storage capacity of 60 acre-feet, the dam poses a high risk due to its lack of hazard potential information and emergency action plan preparedness. Despite these challenges, the dam continues to play a vital role in water resource management for the surrounding area.
As climate and water resource enthusiasts, there is a clear opportunity to advocate for improved risk management measures, including the development of an emergency action plan, hazard assessments, and condition ratings for Monroe Lake Dam. By working with state regulatory agencies and private owners, we can ensure the longevity and safety of this important water infrastructure in the face of changing climate conditions.

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 Monroe Lake Dam
Where does the data for Monroe 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.
