The Tay Catchment. - (The Tay Foundation, 02/02/98)
The Tay catchment covers an area of some 6,475 square kilometres and discharges more water to the sea than any river in the United Kingdom. The headwaters of the Tay and its tributaries rise in the West Highlands and Southern Grampians. The greater proportion of the catchment lies north of the Highland Boundary Fault (HBF), which forms a north-easterly line from Buchanty Spout (R. Almond), to between Dunkeld and Caputh and continuing through the Reekie Linn and Slug of Auchrannie (R. Isla).
North of the HBF, the geology generally consists of hard metamorphic rocks with occasional igneous intrusions. The Loch Tay�Glen Tilt Fault further divides this area, to the north of which is a hard granulite component and to the south a slightly softer schist component.
The region north of the HBF is typically mountainous with the main rivers (Dochart, Lyon, Tummel, Garry, Ardle and Shee Water) flowing through wide straths. The smaller streams are mainly steep and obstructed by waterfalls and often limit access to upstream migration of fish.
The area south of the HBF is characterised by a gentler topography associated with soft sedimentary rocks (mainly Old Red Sandstone). The rivers in the region (Isla, Dean Water, lower Tay, Almond and Earn) are generally slower moving and flow through arable farmland. The soft nature of the rocks and rich soils in this region produce river and stream beds with a greater proportion of sand and silt than those north of the HBF.
STATUTORY POWER OF THE DISTRICT SALMON FISHERY BOARDS:
