Yes that is certainly some sort of guzzler. Looks a lot like on I searched for for some years and finally found up Dolomite canyon. (An interesting story that is too long to tell here, but started with a pencil notation of "WATER" on a hard copy USGS topo map in a library at MIT, but the mark was incorrectly located). Should have (perhaps was formerly) a catch basin upstream, probably some little dam, with a pipe feeding it. The one in Dolomite had a tank like the old radiator water tanks. There was some water in it but the guzzler was not being fed. More tanks = longer time needed between rains to fill them. That is a pretty remote site for one.
