§ 226.23 - Umpqua River cutthroat trout (Oncorhynchus clarki clarki).

(a) The following areas consisting of the water, waterway bottom, and adjacent riparian zone of specified lakes and river reaches in hydrologic units presently accessible to listed Umpqua River cutthroat trout. Adjacent riparian zones are defined as those areas within a slope distance of 300 ft. (91.4 m) from the normal line of high water of a stream channel (600 ft. or 182.8 m, when both sides of the stream channel are included) or from the shoreline of a standing body of water. Figure 9 to this part identifies the general geographic extent of larger rivers, lakes, and streams within hydrologic units designated as critical habitat for Umpqua River cutthroat trout. Note that Figure 9 does not constitute the definition of critical habitat but, instead, is provided as a general reference to guide Federal agencies and interested parties in locating the general boundaries of critical habitat for listed Umpqua River cutthroat trout. The complete text delineating the critical habitat for the species follows. Hydrologic units are those defined by the Department of the Interior (DOI), U.S. Geological Survey (USGS) publication, “Hydrologic Unit Maps, Water Supply Paper 2294, 1986, and the following DOI, USGS, 1:500,000 scale hydrologic unit map: State of Oregon (1974) which is incorporated by reference. This incorporation by reference was approved by the Director of the Federal Register in accordance with 5 U.S.C. 552(a) and 1 CFR part 51. Copies of the USGS publication and maps may be obtained from the USGS, Map Sales, Box 25286, Denver, CO 80225. Copies may be inspected during normal business hours at NMFS, Protected Resources Division, 525 NE Oregon St., Suite 500, Portland, OR 97232-2737, or NMFS, Office of Protected Resources, 1315 East-West Highway, Silver Spring, MD 20910, or at the Office of the Federal Register, 800 North Capitol Street, NW., Suite 700, Washington, DC.

(b) Geographic boundaries. All river reaches accessible to listed Umpqua River cutthroat trout in the Umpqua River from a straight line connecting the west end of the South jetty and the west end of the North jetty and including all Umpqua River estuarine areas (including the Smith River) and tributaries proceeding upstream from the Pacific Ocean to the confluence of the North and South Umpqua Rivers; the North Umpqua River, including all tributaries, from its confluence with the mainstem Umpqua River to Soda Springs dam; the South Umpqua River, including all tributaries, from its confluence with the mainstem Umpqua River to its headwaters (including Cow Creek, tributary to the South Umpqua River). Critical habitat includes all river reaches below longstanding, naturally impassable barriers (i.e., waterfalls in existence for several hundred years) in the following hydrologic units: North Umpqua, South Umpqua, and Umpqua. Critical habitat borders on or passes through the following counties in Oregon: Douglas, Lane, Coos, Jackson, and Klamath counties. Perennial rivers and creeks within the defined areas are also included in the critical habitat designation (but are not specifically named), unless otherwise noted. Critical habitat maps are available upon request from NMFS, Protected Resources Division, 525 NE Oregon St., Suite 500, Portland, OR 97232-2737, telephone [phone]).
