Sedimentation is an important factor in evaluating the habitat of a stream. Here deposits are causing a blockage of base flow, directing water to the banks, causing erosion. In addition, the movement of sediments affects the ability of aquatic organisms to feed and reproduce. Here you can see how flashy Malletts Creek is. After storms, the creek swells dramatically.
Detention ponds are critical to moderate runoff to the creek.
These ponds are required wherever there is new development. Following a storm, Malletts Creek can become turbid - or muddy. This is caused by erosion which leads to sedimentation as small soil particles fall out. Sedimentation inhibits the reproduction of aquatic life. In a stable portion of the Creek, you can see an intact floodplain, abundant streamside vegation, and a stable channel.
