I have a multiband raster (RGB) and I'd like to select out the watercourses to create a new raster.

Examining the data it seems I can do so by selecting blue > 100, Red <100, Green <100. Is there a way to create a new raster based on an sql query, where all pixels that meet the criteria are differentiated from those that don't?

I have the spatial analyst extension. I saw the [Extract By Attributes](http://desktop.arcgis.com/en/arcmap/10.3/tools/spatial-analyst-toolbox/extract-by-attributes.htm) tool, but this just allows me to select by `Value`.

Ideally my end product would be a binary raster that differentiates between those pixels that meet the given criteria and those that do not.
