Mccallie-South Lake Dam dam
Mccallie-South Lake Dam
Mccallie-South Lake Dam, located in Lonoke, Arkansas, was completed in 1950 primarily for irrigation purposes. This private earth dam stands at 15 feet tall and spans 2800 feet in length, with a storage capacity of 170 acre-feet. Situated on the Wattensaw Bayou, this structure plays a crucial role in managing water resources in the area, providing irrigation water for agricultural activities in the region.
Despite its low hazard potential and current "Not Rated" condition assessment, Mccallie-South Lake Dam has not undergone recent inspections or assessments. The dam lacks a spillway and does not have associated structures or outlet gates. While it is not regulated by the state and has not been inspected for compliance or safety recently, its strategic location and purpose make it a key infrastructure for water resource management in the region. Enthusiasts interested in the intersection of water resources and climate change may find this dam's history and functionalities intriguing for further study and understanding of the local ecosystem.
As a non-USACE (U.S. Army Corps of Engineers) structure, Mccallie-South Lake Dam's operations, funding, design, and construction are all managed by private entities. With no state permitting, inspection, or enforcement activities in place, the responsibility for the maintenance and safety of this dam falls solely on its private owner. This unique aspect adds a layer of complexity to the management and regulation of water resources in the area, making Mccallie-South Lake Dam a fascinating subject for water resource and climate enthusiasts seeking to understand the intricate dynamics of private infrastructure in the broader context of water management.

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 Mccallie-South Lake Dam
Where does the data for Mccallie-South 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 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.
