Some of the streams that currently freeze to their beds will retain a layer of water beneath the ice, which will be beneficial to invertebrates and fish Part populations. [ 2IPCCBIODIVERSITE 0 MCLH 21/03/2017 ]

The construction of canals, levees, and other such structures has interfered with normal water cycles upon which successful Wood Stork breeding depends. In a normal cycle, high water levels increase fish Part populations. [ ENDANGERED SPECIES MISSISSIPI PACKET 0 MCLH 21/03/2017 ]
