Instream sediment control is achieved by isolating sediment-laden waters from passing stream flows, thus allowing sedimentation of disturbed waters within the enclosed area. 3. The placement of silt curtains within tidal waters is complex and requires careful planning and design. Inappropriate design can result in unnecessary sediment releases. Temporary Instream Sediment Controls for Low Flows Outlet Blocking An easy method of sediment control is to block the ditch outlet using plywood or a ‘plug’ of clean material (e.g. gravel) at the outlet. Anything used to block an outlet must be removed once the work is completed, and should not be in place from November to June of any year.

Instream sediment control techniques field implementation manual: 1. Currently, assessments of instream sediment conditions are based on aerial photo interpretations of geomorphology and on professional judgment. Collection of up to date information on instream channel characteristics provides a basis on which to make more informed judgments. Water quality data are compared to water quality objectives.
