The River Cononish is the headwater of the River Dochart
– the symbolic source of the River Tay and the
area which produces some of the earliest spring salmon
for which the Tay was famous. Surveys have indicated
juvenile salmon populations are poor and local anecdote
suggests brown trout have greatly declined in 30 years.
Even when stocked with salmon fry, resulting numbers
were still very low.
It is not clear why this should be so as the general
quality of the habitat is good. The Tay Foundation is
supporting an investigation to establish the cause of
this problem. In the first instance the invertebrate
community is being investigated to see whether there
might be some subtle water quality issue and in a second
phase water chemistry analyses may be considered.

The Cononish is the symbolic headwater of the Tay,
whose source rises on Ben Lui seen in the background.
The fish population in this area has declined and investigations
are aimed at finding out why. |
