Christopher O'Gorman, a spokesman for Rodney Strong Wine Estates in Healdsburg, confirmed the tank in Sonoma County sprang a leak Wednesday and wine poured into the Reiman Creek, which carried it to the nearby Russian River.

He said a mechanical failure is believed to be responsible for the leak. The California Office of Emergency Services said 97,000 gallons of wine spilled into waterways, but the winery said that number represents the full capacity of the tank and only about 20 to 25 percent spilled. "We feel like not that much wine got into the waterway. We are investigating the other tanks. We've moved wine out of that area to prevent any future leaks as well," O'Gorman said. Don McEnhill, the executive director of the non-profit Russian River Keeper, said volunteers have been monitoring the situation.

We haven't had any reports of fish kills, certainly the biochemical oxygen demand and the acidity of the wine is going to kill some smaller insect type things that are fish food. This could have been a lot worse," he said. The winery said it worked with a third-party contractor to pump wine out of the river. The state Department of Fish and Wildlife said an investigation is underway and misdemeanor charges and other penalties are possible.
