Average concentration of mercury (µg/kg, ppb) are represented by the red vertical bars and brackets represent one standard deviation in whole-bodies of fish from the Fountain Creek watershed, Colorado, collected in March through May, 2009. Twenty brown trout and two longnose suckers were collected in sites UF-1-through UF-4, a cold-water segment of Fountain Creek; however, three brown trout as well as several warm-water fish were collected below the confluence of Upper Fountain Creek and Monument Creeks at site LF-1. All other fish were collected in the warm-water segments of Monument and Lower Fountain Creeks
