N H Cobb Estate dam
N H Cobb Estate
N H Cobb Estate, also known as N H Cobb Lake, is a private fish and wildlife pond located in Hale County, Alabama. Built in 1964 by the USDA NRCS, this Earth dam stands at a height of 18 feet and spans 800 feet in length, providing a storage capacity of 119 acre-feet of water. The primary purpose of this dam is to support fish and wildlife activities in the area, serving as a vital resource for the local ecosystem.
Despite being classified as having a low hazard potential, the N H Cobb Estate dam has a moderate risk assessment rating of 3. Although it is currently not rated for its condition, the last inspection took place in 1978, indicating a need for updated assessments and potentially a comprehensive risk management plan. With a spillway width of 60 feet and maximum discharge capacity of 250 cubic feet per second, this dam plays a crucial role in managing water resources for the surrounding area.
As a part of the Mobile District in Alabama, N H Cobb Estate serves as a valuable asset for water resource and climate enthusiasts, offering insights into dam construction, management, and the importance of maintaining infrastructure for ecological purposes. With its location on TR-LIMESTONE CREEK and its commitment to supporting fish and wildlife, this site showcases the intersection of conservation efforts and water resource management in the region.
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 N H Cobb Estate
Where does the data for N H Cobb Estate 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.
