Rice Canyon Creek has its source at the head of Rice Canyon at an elevation of 3440 feet in the Santa Ana Mountains at 33°41′54″N 117°24′11″W east of the 4313 foot peak on the north south divide of the range. It is a wash that runs down from the canyon mouth 33°41′07″N 117°27′08″W at 1631 feet to its mouth at its confluence with Temescal Creek near Alberhill, California at an elevation of 1220 feet. Rice Canyon Creek has a tributary, Bishop Canyon Creek which enters the wash on the left a little below the mouth of Rice Canyon at 33°42′05″N 117°24′07″W.Rice Canyon Creek flows in the rainy season in its upper reach but is an ephemeral arroyo in its lower reach below the narrows 0.80 miles above the canyon mouth, and flows on the surface below the narrows only after more heavy rain events, and is dry the rest of the year. Rice Canyon's creek flows during the rainy season below its narrows to its mouth but its surface flow dries up below the narrows about 0.8 miles above its mouth in the canyon during the dry season, and above that in years with severe drought conditions. However some waterholes remain even in the dry years in the upper reach. Much of the wash in modern times has been interrupted by clay mining operations that stops the surface flows of water from Rice Canyon Creek from reaching Temescal Creek.
