- •
The results indicate temporal shifts in the dominant oxygen demanding process in the lake.
- •
Sediment oxygen demand is the dominant process during periods of no-inflow.
- •
Pelagic oxygen demand is the governing process during periods of inflow.
- •
Resuspended sediments at the inlet end of the lake exert a higher oxygen demand than those from the outlet.
- •
External rather than internal loading appears to be the dominant driver of water quality in this lake.
