Updated: 1 December 2007

2.3.4 Reservoirs

2.3.4.3 Example 3
Location of Example: 149°35'21" East, 28°35'52" 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 enclose the partial boundary of the Reservoir or its entirety depending on the topography and method of construction of the Reservoir.
Regional Considerations:
