<p>When the polluted marsh known as <a href="https://en.wikipedia.org/wiki/Ashbridges%27_March" class="extiw" title="w:Ashbridges' March">Ashbridges' March</a> was filled with landfill, three sections were dredged instead for navigation.
</p>
In the west the <a href="https://en.wikipedia.org/wiki/Keating_Channel" class="extiw" title="w:Keating Channel">Keating Channel</a> and the <a href="https://en.wikipedia.org/wiki/Turning_Basin" class="extiw" title="w:Turning Basin">Turning Basin</a> were dredged to a depth suitable for industrial navigation.  At the east end of the marsh a new breach in the barrier sandbar was breached, known as the <a href="https://en.wikipedia.org/wiki/Coatsworth_Cut" class="extiw" title="w:Coatsworth Cut">Coatsworth Cut</a>, enabling navigation to a dredged rump, now known as <a href="https://en.wikipedia.org/wiki/Ashbridges%27_Bay" class="extiw" title="w:Ashbridges' Bay">Ashbridges' Bay</a>.  Ashbridges' Bay and the Coatsworth Cut are only used by pleasure craft.
