The nearest watercourse on the river map is the River Darwen, about 10 m from the middle of Lower Darwen's gauges. It flows into the River Ribble about 22 km 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 Darwen nearest the middle of Lower Darwen'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.
