This category is for WRIA 32 projects crossing multiple spawning aggregations and/or non-priority areas. For reporting on the entire WRIA (Watershed) see the Level 1 Project 'WRIA 32 Walla Walla Habitat Restoration and Protection'.

This category includes four MSA's with the following habitat factors and objectives:

Mainstem Walla Walla River MSA

I.Temperature: not more than 4 days above 72ºF
II.Large Woody Debris: 0.5 to 1 pieces per channel width
III.Embeddedness: less than 10% embeddedness
IV.Riparian Function: 40 to 90% of maximum
V.Channel Confinement: reduce to 40% to 60% of stream length

Mill Creek MSA
Imminent Threats: Fish Passage Barriers (including gravel berms), Fish Screens, Low/Dewatered Streams
