River Eden 

The River Eden is a smaller river, separate from the Tay, but part of the Tay fisheries district. The Eden rises just south of Glenfarg but then flows eastwards through the Howe of Fife, discharging into a large estuary at Guardbridge, just north of St Andrews. For much of its length the Eden has a low gradient and drains one of the most intensively cultivated areas in Scotland.

In character, the Eden looks more like a chalk stream than a typical river in this part of the world. However, the Eden has traditionally had a later run of salmon and is fished over much of its length by the Eden Angling Association. This river is believed to have suffered a lot from agricultural intensification. Loss of spawning gravel is thought to have been an issue and more recently there had been a loss of Ranunculus in lower river. But, compared to other rivers, juvenile salmon grow very fast in the Eden, with many perhaps going to sea as 1 year olds. The river also holds significant populations of brown trout and sea trout.
