According to the Environment Agency source cited by Wikipedia:<br>

<br>
Dowles Brook is 15.5 km long.<br>
<br>
I've just created a relation for our mapping of it, and it only totals 8km:<br>
<br>
   <a href="https://www.openstreetmap.org/relation/12687867#map=13/52.3852/-2.3677" rel="noreferrer" target="_blank">https://www.openstreetmap.org/relation/12687867#map=13/52.3852/-2.3677</a><br>
<br>
The origin, at the western end, is apparently this node:<br>
<br>
   <a href="https://www.openstreetmap.org/node/6314143144" rel="noreferrer" target="_blank">https://www.openstreetmap.org/node/6314143144</a><br>
<br>
where the source seems to be the convergence of two other waterways:<br>
Raveney Brook and Lem Brook.<br>
<br>
Can anyone explain the discrepancy? Is one of the latter two waterways<br>
also known as Dowles Brook? Or labelled in error?<br>
<br>
I have one source that gives "The Dowles Brook flows ... from its<br>
source at Bagginswood, Shropshire [SO6881]", but a) it's not a<br>
particularly reliable source and b) there are three streams that start<br>
near that location, each of which eventually flows into what we have<br>
as Dowles Brook, but are unnamed on OSM:<br>
