Description

Abstract: The Little Walla Walla River and Spring Branch system is an anomaly when compared to most river systems. This non-linear combination of distributaries and an alluvial fan of spring fed creeks is treated by various state agencies and the local community as either a water conveyance network or natural stream, depending on the location being considered, or the time of year. This conundrum needs to be described and evaluated so that a coordinated approach can be developed and implemented to improve these unusual streams and the farms, fish, and wildlife that depend on them. This assessment consolidates information on the Little Walla Walla River and springs area with regards to historic and current flows, water use, land use, fish presence, habitat conditions, fish passage barriers, and water quality. This can then be utilized in developing a plan that aim to improve and preserve the environmental and economic health of this stream network, and to better define management and enhancement options. An Initial Action Plan of Goals and Actions is put forward as a discussion framework. Some of these actions are just conceptual, others are ongoing, but can be expanded to a greater scale.
