The reddish hue the Hudson River has taken on in recent weeks appears to be the result of storm water runoff from all the rain during Tropical Storm Irene.
Initial water quality test results from the Department of Environmental Protection indicate lower than usual transparency, meaning there's less sediment in the water.
DEP spokesman Farrell Sklerov said oxygen levels appear to be within normal expected ranges. Biological tests that check fecal coliform counts are still unavailable.
Officials say the water is safe for boaters.
