White sturgeon (Acipenser transmontanus) recovery strategy: chapter 4
In the Nechako system, white sturgeon occur from the confluence with the Fraser River, upstream to Cheslatta Falls including Fraser Lake, and through much of the Stuart River watershed, a major tributary. This population is referred to as Nechako River white sturgeon. Data indicate limited movement of Nechako white sturgeon into the Fraser; however, feeding at the Fraser River confluence has been observed. Current distribution in the Nechako may be limited by population declines and the alteration of flows (and related effects) below Kenney Dam (NWSRI 2005).
The information base for the Nechako white sturgeon population is substantial, based on many years of intensive study. High use habitats have been identified for all life stages, and this information is summarized in Table 9. As additional information is collected through recruitment failure diagnosis, it will become possible to refine existing information on critical habitat.
Table 9. Summary of information base for white sturgeon critical habitats in the Nechako system. An empty cell means that the life stage does not consistently use the habitat. The table has two main columns from left to right: Location (see Figure 14 for basin overview) and Confirmed (Checkmark), Suspected (S), or Possible (question mark) Use by Life Stage and Degree of Use (H=High, M=Moderate, L=Low). The latter column has seven sub-columns from left to right: Spawn, Yolk sac larvae/feeding larvae, Early juvenile, Late Juvenile and Adult, Overwintering, Staging, and Overall assessment. Directly below column headings are 14 rows, read from left to right.

Table 10 summarizes the critical habitat function(s), features and attributes, to the extent possible, for the Nechako population of white sturgeon.
Table 10. This table provides a summary of the biophysical features, functions, attributes and locations of critical habitat for Nechako white sturgeon. The first column describes the geographic locations of the critical habitat, which encompass areas within the Nechako River where white sturgeon reside. The second column indicates the life stage that uses each respective critical habitat area. The third column indicates the function that the particular life stage undertakes in each area. The fourth column describes the critical habitat feature that provides the function, and the fifth column details the attributes that the critical habitat feature must have in order to provide the biological function needed to support Nechako River white sturgeon survival or recovery. The final column contains notes.
The following locations of the critical habitat’s functions, features and attributes have been identified using the critical habitat parcel approach.

Table 11. Geographic Coordinates of Critical Habitat Areas for Nechako River white sturgeon. A footnote on the word “coordinates” in the previous sentence states the following: Coordinate points were digitized using various orthophotos provided by Fisheries and Oceans Canada. The resolution of the various orthophotos varied significantly - ranging from 0.2 m cell size to 24 m cell size. This should be taken into consideration when evaluating the accuracy of the coordinates associated with these points. For geographic coordinate points, their boundary represents the annual high water mark (Hatfield et al. 2012). Note: For the Nechako River, relative locations are measured as “river kilometers”, which increase from the river mouth (Rkm 0) upstream to the farthest extent possible.

12 Coordinate points were digitized using various orthophotos provided by Fisheries and Oceans Canada. The resolution of the various orthophotos varied significantly - ranging from 0.2 m cell size to 24 m cell size. This should be taken into consideration when evaluating the accuracy of the coordinates associated with these points. For geographic coordinate points their boundary represents the annual high water mark (Hatfield et al. 2012).
Note: For the Nechako River, relative locations are measured as “river kilometers”, which increase from the river mouth (Rkm 0) upstream to the farthest extent possible.
