There is a public right of navigation between [[Pool Quay]], near [[Welshpool]], and Stourport. However this stretch of the river has little traffic, other than small boats, canoes and some tour boats in Shrewsbury. Below Stourport, where the river is more navigable for larger craft, users must obtain permits from the [[Canal & River Trust]], who are the [[navigation authority]]. During spring [[freshet]] the river can be closed to navigation.

At Upper Parting above Gloucester, the river divides into two, and flows either side of [[Alney Island]] to Lower Parting. The West Channel is no longer navigable. The East Channel is navigable as far as Gloucester Docks, from where the [[Gloucester and Sharpness Canal]] provides a navigable channel south. Between the docks and Lower Parting [[Llanthony Secunda|Llanthony Weir]] marks the Normal Tidal Limit (NTL) of the East Channel of the river.<ref>{{cite web|url=http://getamap.ordnancesurvey.co.uk/getamap/frames.htm?mapAction=gaz&gazName=p&gazString=GLOUCESTER|title=OS Maps – online and App mapping system – Ordnance Survey Shop|access-date=28 February 2009|archive-date=31 January 2009|archive-url=https://web.archive.org/web/20090131201355/http://getamap.ordnancesurvey.co.uk/getamap/frames.htm?mapAction=gaz&gazName=p&gazString=GLOUCESTER|url-status=live}}</ref>

In the tidal section of the river below Gloucester, the [[Gloucester Harbour Trustees]] are the competent harbour authority. The Trustees maintain navigation lights at various points along the river (including on Chapel Rock and Lyde Rock, and [[leading lights]] at Slime Road, Sheperdine and Berkeley Pill).
