Prevent Introduction of Fine Materials

Gravel, either obtained onsite or from a commercial source, will be appropriately screened (by size separator) prior to being placed in the river to avoid introduction of fine material. On-site gravels will be screened and sorted; gravels imported from a commercial source will be clean-washed and of appropriate size. Placement will be overseen by a qualified individual and implementation timing will be determined based on the least amount of overlap, or impact on, all sensitive resources that may be affected and the timing of their use of the receiving area.
