Hatch Side Channel Restoration Projects

In 2007 the North San­tiam Water­shed Coun­cil started work­ing with a local landowner to assist with a failed cul­vert that was block­ing river flow into the Hatch Side Chan­nel, a side chan­nel located in the Lower North San­tiam River near the Hatch Airstrip west of Stay­ton. The Coun­cil was able to obtain fund­ing to replace the under­sized cul­vert with a larger cul­vert open­ing up the chan­nel to year round water flows and pro­vid­ing migrat­ing salmonids year round access to valu­able spawn­ing and rear­ing habi­tat.  This cul­vert replace­ment project piqued the inter­est of sur­round­ing neigh­bors who wanted to join in on the Hatch Side Chan­nel restora­tion efforts. Work­ing with sev­eral landown­ers  and part­ners the Coun­cil was able to com­plete two project phases over five years (2007–2012). The fol­low­ing is a sum­mary of accom­plish­ments achieved dur­ing each project phase:

Phase I: Hatch Air­port Fish Pas­sage and Habi­tat Restora­tion Project:

  • Replace­ment of a failed, under­sized cul­vert with an over­sized coun­ter­sunk cul­vert to improve fish pas­sage and main­tain func­tion of a pri­vate airstrip.
  • Place­ment of sev­eral engi­neered log jams in the side chan­nel and addi­tional habi­tat logs through­out the wetland/floodplain area.
  • Removal of nox­ious weeds on approx­i­mately 3 acres sur­round­ing the side channel.
  • Place­ment of native plants around the cul­vert inlet and out­let for ero­sion con­trol and to start estab­lish­ing a ripar­ian buffer.

Phase II: Hatch Side Chan­nel Habi­tat Restoration

  • Two addi­tional under­sized cul­verts were replaced with fish pass­able sized cul­verts that
    meet ODFW stan­dards.
  • Addi­tional native ripar­ian buffer areas restored along the side channel.
  • Place­ment of 5 addi­tional engi­neered log struc­tures improv­ing chan­nel complexity.
