River levels vary a lot in these parts, in a dry summer you can find yourself stuck on a sandbank and for most of the rest of the year high water can prevent you getting under some bridges. Gauge map (below) displays data from EA water level gauging stations, simply enter the location or name of the river you’re interested in. Heights in metres are based on the normal level for each place.

If you want something more portable when you’re on the river try RiverApp for Android and iPhone.
