Book Description
Our analysis of project impacts on fish and wildlife resources is based on a literature review; personal communication with recognized experts; field investigations and surveys; preliminary engineering and other information provided by the Corps; and a projection of future conditions using current land-use information and analysis provided by the Corps. Our analysis will not remain valid if the project, the resource base, or anticipated futures change significantly. This report is accompanied by separate substantiating reports for the three major segments of the American River Watershed Investigation: Auburn area, Lower American River area, and Natomas area.

Book Description
This appendix presents the real estate requirements for the selected plan to provide critically needed flood protection for urban areas along and adjacent to the lower American River in the vicinity of Sacramento, California. The Corps' authorization for its one-year reconnaissance study was included in the 1987 Appropriations Act. Authorization for additional study was included in committee language accompanying the Fiscal Year 1988 Continuing Appropriations Act (Public Law 100- 202, dated December 22, 1987).

Book Description
This appendix has categorized comments by subject (a listing of the subjects can be found in the Table of Contents). Some comments did not fit neatly into one specific subject category, especially if the comment addressed several issues. In those cases, comments were generally categorized under what was considered the major point of the comment. Regardless of how they were categorized, each comment was given equal attention in generating a response. Not all comments warranted an individual response; therefore, your comment may be grouped with others of a similar nature addressed by one response.

Book Description
Originating in the Sierra Nevada, the North and Middle Forks of the American River join just upstream of the city of Auburn (Figure 1). From the North and Middle Forks confluence, the river flows past Auburn before entering Folsom Lake. Flows are released from Folsom Dam into Lake Natoma, which serves primarily as a reregulating reservoir. From Nimbus Dam, water is released downstream into the lower American River. It then flows through the American River Parkway (Figure 2), located in the densely populated Sacramento metropolitan area, for a distance of 23 miles before reaching its confluence with the Sacramento River. The average annual runoff is about 2.7 million acre-feet. The annual flow regime of the river, however, has changed significantly since construction of Folsom and Nimbus Dams in 1955. Nimbus Salmon and Steelhead Hatchery is located just below Nimbus Dam (Figure 3). Built in the early 1950's to compensate impacts of the Folsom project, it is operated by the California Department of Fish and Game under contract with the Federal Government. The lower American River floodplain is about 4,800 acres in size with an additional 4,000 acres of undeveloped adjacent lands. Of the 8,800 acres, about 5,000 acres are administered by Sacramento County as the American River Parkway (Figure 2). The parkway supports over 5 million visitor-use days annually with an estimated nonmarket value of $96 million (California Department of Fish and Game 1986), making it a very valuable regional asset.
