Instream Passage Improvement



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."

When acquiring water to improve passage, the Water Conservation and Irrigation Practices and Water Transactions work elements may be more appropriate.

The Instream Passage Improvement work elements are:
69. Install Fish Screen
80. Install Siphon
84. Remove or Install Diversion
85. Remove/Breach Dam
184. Install Fish Passage Structure
