Altnaghree Burn
Altnaghree Burn is a tributary of the River Dennet. It has some of the Foyle area’s highest densities of native fish including Atlantic salmon, sea trout and brown trout.
The lower reaches of Altnaghree are dominated by a series of small waterfalls which limit the movements of migratory fish to certain flow conditions.
Typically, returning salmon and sea trout begin ascending the Altnaghree in suitable spates from July and stay in deeper water until spawning time. Spawning usually starts in September for brown trout, in October for sea trout and December for Atlantic salmon.
Over the past ten years, Loughs Agency has undertaken a number of pre-spawning sea trout surveys. A better understanding of fish numbers, distribution and habitats has helped us to develop a series of habitat improvements.
At Altnaghree, these include:
Loughs Agency is always eager to develop collaborative projects with local partners. If you belong to an organisation which is interested in protecting and improving local aquatic habitats, please contact mark.mccauley@loughs-agency.org
