For stream habitat restoration to be effective it must be designed properly. Structures placed or sized wrong will not work. Stream restoration projects throughout the world have been criticized for the high failure rate due mainly to the placement and sizing of structures without proper consideration of the natural processes that form and maintain stream structure.
The instream locations and sizing must be determined by trained and experienced individuals and approved by AAS staff if the work is funded under the NSSA Adopt-a-Stream Program or done under the Program permit.
