The relative importance of sediment effects on the benthic environment has been recognized by many authors. Sediment concentrations that may have only minor impact on organisms within the water column may present major difficulties for those on and within the substrate once sediment deposits. The current provincial emphasis on sediment measurement within the water column, primarily by means of continuous turbidity monitoring, must be supplemented by a concerted effort to identify reliable test methods for depositional sediment. Identification of methods must be a priority at this early stage of water quality management under the Forest Practices Code. Accordingly, the objective of this document is to review and recommend to water quality resource managers quantitative sampling methods for depositional or transient fine grained particles in stream environments. The method must be reliable, relatively inexpensive, and not overly labour intensive. To achieve this objective, this document has several goals, namely to: review sediment impacts to various life forms in flowing water environments; establish the relative importance of monitoring deposited and suspended sediment; identify methods for the collection of sediment in flowing water environments; provide results of initial field testing of selected methods; identify preferred methods based on our field tests and available literature; and recommend actions that will improve the impact assessment of benthic environments in flowing waters.
