section L. At this point, several YOY grayling were captured in 

 the main stem of the river, downstream from section L. No YOY 

 had previously been captured in this location. Since none of the 

 YOY captured below section L had been marked, it is impossible to 

 conclude that the YOY in section L all went downstream. 

 However, circumstantial evidence would seem to indicate that at 

 least some did move downstream.
