Please click on the above image to view a larger, clearer image in a new window.  The graph shows, upstream counts (blue bars) and down counts (red bars) per day between Feb 2006 and Jan 2007.  Also shown is flow at Knapp Mill gauging weir (blue line) and water temperature (red line).
The data on the graph relates to fish detected by the counter (Salmon and Sea Trout) and is not an overall estimate of the population at this stage as it does not account for upstream and downstream fish which are not detected by the counter.  We are currently using video validation to determine the detection rate of the counter and will display this here when completed.
