A first iteration of this document was completed in September 1998. The analysis generally follows the federal guide for watershed analysis (Version. 2.2, August 95) although some modifications were made, such as combining chapters to reduce redundancies. This is a document which is still evolving and will be updated as new information becomes available. The data in this document were the best available, although in some cases there were little relevant data available. Management opportunities for this analysis area must be considered in light of the checkerboard land ownership pattern of BLM- administered land; cooperative programs with adjacent ownerships are necessary to achieve optimum results in restoration opportunities. No warranty is made as to the accuracy, reliability or completeness of the data or maps contained herein.

M-1 Preface The Northwest Forest Plan (NFP) is a regional ecosystem management plan which was initiated in 1994 by federal land management agencies. The plan requires that watershed analyses be completed on all federal lands within the range of the northern spotted owl. Watershed analysis provides the foundation-laying data structure needed to support the ecosystem management objectives described in the NFP. It also enhances the agencies’ abilities to move away from species and site-specific management, and towards systems management. Although watershed analysis is not a decision-making process, the results of a watershed analysis establish the context for subsequent decision-making processes, including planning, project development, and regulatory compliance. Most NFP watershed analyses focus on one fifth-field watershed and the subwatersheds located within it. This watershed analysis, however, will focus on seven subwatersheds located within the following four fifth- field watersheds (listed from N to S): the South Yamhill River, Mill Creek, Rickreall Creek, and the Luckiamute River. All of the lands, both federal and private, contained within the four adjacent fifth-field watersheds will be referred to as the “megawatershed area” (See Map 1, p. C-2); the seven conterminous subwatersheds, which contain 96% of the BLM lands within the megawatershed, will be collectively referred to as the “analysis area” (See Map 2, p. C-3). Where appropriate, specific watersheds or subwatersheds will be referenced if actions, their impacts, or other issues warrant a more detailed approach. The primary reasons for combining four fifth-field watersheds into one analysis are (1) the small amount of federal ownership, primarily Bureau of Land Management (BLM) lands, and (2) the fragmented nature of this ownership. It was also felt that the ecology and issues within the upland forest environment associated with these watersheds are not significantly different to justify separate analyses. If pivotal differences surface during the course of this analysis, then it may be necessary in future analyses to further subdivide this boundary. This analysis is tiered to the following documents (for full citations, see “References”): 1.
