This information was transferred on-screen to 1:24000 scale streams derived from Cartographic Feature Files (CFF). In the case of double-line streams, the right bank (looking downstream) was attributed and the left bank was removed. In the case of lakes & other large waterbodies, a new line was digitized down the approximate center of the waterbody and attributed. For stream segments occurring on the quads between the KNF westside & eastside for which 1:24000 data does not exist, stream segments were brought in from 1:100000 data (bad boy! bad boy!).

Item Value Description The attribute for species presence is composed of two parts: the first number indicates historical occurrence status and the second number indicates verification status. Codes for historical occurrence are: 0 Non-native: fish species not currently present, nor documented to have been native to the location. 2 Extirpated: fish species not currently present, yet historic surveys, records, and/or literature provide documentation of historic presence as a native species to the location. 3 Native: fish species native to location 4 Introduced: fish species literature and historical records provide documentation that species was not native to the location. Codes for species verification are: 1 Present: species are present as documented by recent (1985 and newer) snorkel surveys, visual surveys, electrofishing and other collection methods. 2 Suspected: presence of species is suspected but recent (1985 and newer) surveys have not been conducted to verify presence, nor has species been otherwise documented within a recent timeframe. 3 Unknown: presence of species is not suspected, surveys have not been conducted, or the species has not otherwise been documented. 4 Potential: species not currently found, yet recent (1985 and newer) surveys indicate that suitable habitat is present. Historical records, written and oral, may/may not indicate species presence in the past. 5 None: no documented species presence or suitable habitat. 6 Present in very low numbers: species are present as documented by recent (1985 and newer) snorkel surveys, visual surveys, electrofishing and other collection methods. Example of complete code: chinook fall = 31: Fall Chinook is native (3) and present (1) chinook_spring = 24: Spring Chinook is extirpated (2) but potential (suitable habitat is present).
