Project Goals and Objectives

The project is located on Thirtymile Creek, approximately 17 miles from the mouth. Thirtymile Creek is a tributary to the John Day River and the John Day River is drains into the Columbia River. It is approximately 5 miles south of Condon in Gilliam County. The major watershed issue for this reach is intermittent flow during the summer months. The reaches upstream and downstream have perennial flow and this project aims to extend those wetted reaches. This project will use various floodplain connection actions to create pool habitat and extend perennial flow. Once perennial flow is established riparian plantings will begin. A riparian fence currently protects the reach.

Structure Construction Elements

BDAs and PALS were constructed following the Low-Tech Process-Based Restoration Design Manual.
