Landscape impacts
As the reservoir fills, the previous river landscape will become a lake. This is difficult to consider a positive or negative impact objectively.
There are potential aesthetic impacts including erosion scars, trapped garbage, and protruding impounded structures, especially at low reservoir levels. The EIA states that effective reservoir management can minimize these impacts. When the reservoir is drawn down too often and too rapidly, there will be more landscape effects visible.
Eutrophication and sedimentation represent landscape effects as well as health and biological impacts.
These impacts will occur most noticeably during the dry season, especially if water use is high or the season is unusually harsh or long.
The EIA suggests operating the reservoir above Minimum Operating Level to mitigate this, but ultimately the severity of landscape effects will depend on seasonality and levels of water use.
