Obstructions to the Passage of Fish- 



1. Dam dykes disused, built, or in prospect : — None. 



2. With regard to the observance of bye-laws in respect of dams, lades, and 



hecks, the provisions of the bye-laws are satisfactorily attended to. 



3. Fish passes built or in prospect : — None. 



4. Natural obstructions not yet dealt with are almost too numerous to 



mention, as practically all tributaries of the loch are impeded by 

 natural falls, many of which are quite impassable. The most 

 important is the Pot of Gartness, which is only passable in a flood, 

 and which makes about 12 miles of the Endrick spawning ground 

 difficult of access. The proprietors will not consent to the pass being 

 made easier for fish. 



Pollutions— 



1. The existing pollutions are many and grievous. The Leven is foul with 

 chemicals and dyes from the turkey red and bleach works on its 

 banks, several of which make no effort to clean their effluents. It is 

 also putrid with sewage effluents, none of which are treated before 

 entering the river. During June and July 1905 the river was 

 impassable during the drought for migratory fish, and the flesh of the 

 fish hanging about the mouth of the Leven became tainted and un- 

 saleable. The Clyde is polluted with sewage and other pollutions. 



L Kemedial measures : — None are being taken by those at fault, but the 

 Association is attempting to interdict the Western District Committee 

 of the County Council of Dumbarton from discharging the sewage 

 from two new sewers into the Leven at Alexandria without adequate 

 treatment. Interim interdict has been granted. 

 The city of Glasgow's sewage scheme will take some years yet before it 

 is fully in operation as regards the Clyde.
