Reedley police say 35-year-old /*Antonio Orosco*/, 35, of Dinuba went under the water near Reedley Beach around six o'clock Sunday night.
Investigators say Orosco was trying to swim to the other side of the river when he likely became exhausted.
Witnesses tell Action News, Orosco yelled for help, that's when two other men jumped into the water to try to help him, but the current was just too quick for them.
Police say it doesn't appear as if Orosco was drinking alcohol before he went into the water.
