The February– May density represents the mean of nine surveys dates from February 4 to May 27. The June density represents the mean of June 9 and June 23. Sites include four west shoreline sites (open circles), four east shoreline sites (solid diamonds) and one site on Mercer Island (cross mark). The distance to the Cedar River for the Mercer Island site includes the distance from Coleman Point to South Point (see Figure 2). 9
