To the east of the Campus is the Mill Creek watershed, which is about 21,000 acres, and includes land in both Walla Walla and Umatilla Counties. The watershed is a small part of Umatilla National Forest, which also sprawls across the state line and encompasses approximately 1.4 million acres. Most practices within the national forest are regulated by the federal government. Hunting, however, is regulated in the forest according to state laws. Links to information on hunting permits and seasons can be found below.
Rules differ between the Mill Creek watershed and the rest of the national forest.
While hunting is regulated by the states of Oregon and Washington in the national forest, in the watershed it is regulated jointly by the federal and state governments and the City of Walla Walla. Furthermore, no logging is allowed in the Mill Creek watershed. The following resources are intended to help present and potential landowners in Walla Walla and Umatilla Counties, and especially along upper Mill Creek, to learn about land use policies that might pertain to them. Walla Walla County Regional Planning is in charge of zoning for the rural areas of that county. In Umatilla National Forest, land is managed by the federal government.
