The instream passage improvement work elements describe the installation of any type of structure that is intended to aid fish passage, or the removal of structures that impede fish passage. The design of such structures is typically split out as its own work element: WE# 175, Produce Design and/or Specifications.
For instream channel excavation and realignment, see WE#30, Realign, Connect, and/or Create Channel.
