The USGS has a KML map of their stream gauges and water quality sensors in the US. Here's a good starting point: <a href="http://water.usgs.gov/wateralert/">http://water.usgs.gov/wateralert/</a><div><br></div><div>Getting an embeddable realtime view can be more difficult - I have a regional example here <a href="http://www.ce.cmu.edu/~wquest/Dunkard%20Images/SensorMap.html">http://www.ce.cmu.edu/~wquest/Dunkard%20Images/SensorMap.html</a></div>
<div><br></div><div>Having worked on a water data research project, there are several standards and data models being discussed and used by researchers. The USGS has shapefiles and IDs of water catchment areas for each major stream - that'll save you a great deal of trouble with DEM terrain data. You don't tend to see these files or stream data online, because the science is mostly done with desktop GIS and rarely publicized. I believe that the NSF, EPA, and local governments were backing <a href="http://his.cuahsi.org/">http://his.cuahsi.org/</a> and <a href="http://water.epa.gov/scitech/datait/models/basins/index.cfm">http://water.epa.gov/scitech/datait/models/basins/index.cfm</a> for sharing information on streams. It would be good to have tie-ins to these successful programs.</div>

<br>
I like your idea, but there are many issues to discuss.<br>
<br>
1. What is the goal?<br>
Depending on users interest (hydrologists, biologists, ..), "average" stream can be represented as line or polygon.<br>
Set of attributes depends on user needs. Even simple water level changes in time. Without some standarisation (mean yearly level?) this will be mixture of everything. And such attributes are not easy to get.<br>
<br>
Geometry based on recent ortophotomaps with basic set of attributes (stream name(s); some "average" discharge and velocity?) could be start point.<br>
<br>
2. Relation to OSM.<br>
It can be seen as subset or extension of OSM. And probably those two sets will be used together. Close cooperation with/within OSM?<br>
<br>
3. Additional data<br>
What about water level gauge stations?<br>
<br>
Anyway - great idea!<br>
<br>
regards,<br>
Robert<br>

Hi,<br>
<br>
I find myself wondering if there is a possibility of starting an "open<br>
stream map" project in a similar way to open street map? With the idea<br>
that this might be connected to an invasive plant species effort too...<br>
<br>
It is an interesting idea -- roads are relatively stable. Streams have<br>
additional attributes, like water levels.<br>
<br>
Any reactions or ideas on how this might be started?<br>
<br>
Cheers<br>
