If a dike is constructed to hold water, suspended sediment and turbidity decreases; if dike is constructed as flood control measure, 

suspended sediment and turbidity will increase because of erosive effect of flowing, channelized water.

Surface water temperature is dependent on site conditions and location of dike.

Dikes will retain water benefiting some species, however if placed in floodplains aquatic habitats will be fragmented.
