However, how much value is there in bringing in all of the stream data <br>

I can see for example, the value in bringing in named streams. But there <br>
are huge numbers of smaller (unnamed) streams.<br></blockquote><div><br></div><div>It's not a bad idea, as it would let anybody needing water in the bush, know that there's a creek over there, & also let you know that if you go this way, you may get wet feet! :-)</div><div><br></div><div>But, do DCS Base & Topo differentiate between permanent & intermittent creeks?</div><div><br></div><div><div><div dir="ltr" class="gmail_signature"><div dir="ltr"><div><div dir="ltr">Thanks<div><br></div><div>Graeme</div></div></div></div></div></div></div><br></div></div>
