Navigation Limits and Levels

The Lower and Upper Avon is navigable over 46 miles (74km), with 17 locks along it's course, from Tewkesbury to Alveston weir above Stratford-upon-Avon. The Higher Avon is a planned extension of the Navigation to link-up with the Grand Union Canal. More information on this project can be obtained from the Stratford and Warwick Waterways Trust.

The River Avon, has junctions with the Stratford Canal at the top of the navigation, and the River Severn at the bottom, and forms part of a navigable 'ring' that includes the Worcester and Birmingham Canal. For more information, see Links.

River Levels and Gauges

Unlike a canal, the water in a river is continually flowing, and it's rate of flow and level varies. After heavy rain in the catchment area, levels can rise, and/or the rate of flow increase to a point where navigation can be hazardous.

The Trust has installed water level gauges at every lock designed to indicate the water level in each stretch of the river and help you gauge whether it is safe to proceed. Check the water level against the colours on the gauge, and compare it with the advice on the sign.

RED         Danger - stop and moor your boat.

ORANGE   Increased current, proceed with caution.

GREEN     Normal navigable level.

The Trust has also set up River watch, which is a network of web cams and links to the EA river gauges that can be viewed through our web site on your PC or smart phone. Please view this on our River Watch Page link here.
