ANNUAL REPORT 



OF 



THE INSPECTOR OF SALMON FISHERIES 

 FOR SCOTLAND. 



MR. CALDERWOOD'S REPORT. 



Fishery Board for Scotland, 

 April 1908. 



I have the honour to submit my report for the year 1907. 



Forth. 



In my report for the year 1904 I stated that arrangements had 

 been made for the erection of a new salmon pass at the Loch 

 Yennacher outlet. This pass has been constructed by the City of 

 Glasgow Water Commissioners below the gauge-house, where the 

 water of the loch flows into what is called " the cut." Four passes 

 were originally constructed at this outlet in order that the ascent 

 of salmon might be secured at different levels of the loch. These 

 passes were, however, found to be unsuitable, being too steep, and 

 necessitating abrupt rises from a series of short rectangular 

 pools. As a matter of fact, it was never ascertained with certainty 

 that salmon ever ascended to Loch Vennachar by those passes, 

 and in consequence several modifications were made upon the 

 natural channel of the river to increase facilities of ascent in this 

 direction. In all probability all salmon found in Loch Vennachar 

 or the streams above, during recent years, found their way up by 

 the natural channel, although fish were very frequently seen in 

 •'the cut" and in the lower pools of the old passes. An attempt 

 was even made to shut fish out of " the cut " altogether, so as to 

 prevent a temptation to fish-snatching which rather easily 

 presented itself.
