The 392-acre Water Tower Fire in Utah County was officially 60 percent contained as of Tuesday morning, but most crews assigned to the blaze had been pulled off for other duties. âThis fire is pretty much out, but weâre being cautious, making sure,â Fire Information Officer Shayne Ward said. The fire, sparked Saturday by a hot 50-caliber bullet casing fired from a makeshift gun range site about 1 mile northeast of Alpine, should be declared 100 percent contained by Thursday.
