Updated:   11 December 2006

2.3.5 Reservoirs

2.3.5.3 Example 3
Location of Example: 149o35'21" East, 28o35'52" South,
Distinctive Characteristics:
  • Large Flood Irrigation Reservoirs can be identified by related infrastructure, such as Cotton Gin facilities that require Flood Irrigation practices.
  • Dam Walls are absent from naturally occurring Lakes.
  • Dam Walls can be constructed from both concrete, stone and earthen materials. Each will display a different signature on multispectral imagery.
  • Dam Walls may cover the partial boundary of the Reservoir or its entirety depending on the topography and method of construction of the Reservoir.
Regional Considerations:
