Threlkeld is a village and civil parish in the north of the Lake District in Cumbria, England, to the east of Keswick. It is in the historic county of Cumberland. It lies at the southern foot of Blencathra, one of the more prominent fells in the northern Lake District, and to the north of the River Glenderamackin. The parish had a population of 454 in the 2001 census, decreasing to 423 at the Census 2011. Part of the parish lies within the Skiddaw Group SSSI.
The nearest watercourse on the river map is the River Glenderamackin, about 120 m from the middle of Threlkeld's gauges. It flows into the River Greta about 540 m downstream.
A gauge downstream shows water that has already passed this point; one upstream sees it first. Distances along the river are from the point on the River Glenderamackin nearest the middle of Threlkeld's gauges. From Ordnance Survey’s river map (OS Open Rivers), which leaves out small streams, ditches and culverts, so a nearer one may exist. This describes where water goes on the map; it says nothing about flooding at any address. Contains OS data © Crown copyright and database rights 2026.
