The effects of sedimentation on the aquatic biota
A review of the effects of sedimentation on aquatic biota is presented. The detrimental effects of increased suspended and settled sediments on fish, bottom invertebrates, and primary productivity are documented. It is shown that the upper tolerance level for suspended sediment is between 80-100 mg/...

A review of the effects of sedimentation on aquatic biota is presented. The detrimental effects of increased suspended and settled sediments on fish, bottom invertebrates, and primary productivity are documented. It is shown that the upper tolerance level for suspended sediment is between 80-100 mg/l for fish, and as low as 10-15 mg/l for bottom invertebrates. Recovery of the aquatic biota from increased sedimentation is dependent on the severity of sediment additions and the discharge level of the rivers or streams. Recovery from short-term additions of sediment is usually complete within one year. The use of remote sensing and biomonitoring to locate sources of sedimentation is discussed.
