Teanaway

North Fork Teanaway

The Mid-Columbia Fisheries (MCF) proposed to restore Teanaway River complexity by placing up to 1,000 pieces of wood at strategic locations along 12 miles in the NF, MF and WF of the Teanaway River, which is the largest undammed tributary to the Yakima River located northwest of Ellensburg. This work was planned to complement large wood trapping structures designed and installed under SRFB #17-1177. MCF was only able to complete wood replenishment in the NF Teanaway and re-grading along Indian Creek within the timeframe of the grant. The complexity of design and permitting for restoration on the Middle and West Fork Teanaway Rivers are being tackled seperately and are anticipated to be completed in 2025 and 2026

MCF and the Yakama Nation (YN) placed 1000 pieces of unanchored large wood in 1.5 miles of the North Fork Teanaway (approximately RM 4.6 – 5.6 and 6.3 – 6.7) in 2019 using helicopter and ground-based equipment. The work was completed concurrently with the construction of six large wood trapping structures at RM 4.7 and RM 5.2, funded under Salmon Recovery Funding Board (SRFB) which were designed to trap the replenishment wood and build jams.

In 2020, MCF and YN re-contoured over 5000 feet of artificial ditch networks in Indian Creek (left bank tributary to the NF Teanaway) to reduce artificial drainage, and rearranged logs throughout the Indian Creek floodplain to improve the function of a previous large wood placement project implemented by the YN (no new structures were installed).

Also in 2020, MCF and YN placed approximately 1000 pieces of unanchored wood using ground-based equipment between NF Teanaway RM 5.8 – 6.2, 7.8 – 8.3, and 8.6 – 8.7. This work was funded by Yakima Basin Integrated Plan , Yakama Nation BPA, and NOAA Fisheries grants.

Additionally in 2020, MCF built three more engineered large wood trapping structures at RM 6.1 – 6.2. MCF and YN placed approximately 1000 pieces of unanchored wood using ground-based equipment further upstream, in a one-mile reach that had not received wood from the helicopter the year before (NF Teanaway RM 5.8 – 6.2, 7.8 – 8.3, and 8.6 – 8.7).

In 2021, MCF and YN built one final wood trapping structure at NF Teanaway RM 5.9  We placed additional wood and breached portions of a berm at the same location.

This was the first phase of the Teanaway Aquatic Restoration. Work in the West Fork and Middle Fork are being planned for implementation in 2025, 2026 and 2027. This will provide a cumulative restoration footprint of nearly
