[2] It is the main spawning area for Eden spring salmon, but is primarily a trout fishery.

[1] The river is held back by the Wet Sleddale dam, and so flows at a fairly consistent level (between 0.33 m and 1.8 m for 90% of monitoring time), with the highest level ever recorded at the River Lowther (2.93 m) occurring at Eamont Bridge, Beehive, on Sunday 6 December 2015.

[4] It may come from Brittonic lǭwadr, "a washing or bathing place",[5] which would give it the same etymology as Lauder, Scotland.

Alternatively, it may come from Old Norse lauðr + á, meaning "foamy river".
