Two mapped watercourses are about the same distance from the middle of Wholsea Grange's gauges: Main Drain (about 40 m) and Egremont Drain (about 50 m), so this page cannot say which one is nearer to you.
Distances along the river are from the point on each watercourse nearest the middle of Wholsea Grange'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.
