Stepping out for a good cause, Maggie Gyllenhaal attended the 2013 Riverkeeper's Fishermen's Ball at Pier 60 in New York City on Tuesday (April 16).
The 35-year-old actress sported a casual ensemble as she posed on the "green" carpet wearing knee-high black boots, a pattern skirt and fur jacket.
Riverkeeper is a nonprofit organization that is dedicated to helping protect the Hudson River as well as advocating for clean drinking water in New York State.
This year, Oscar-nominated actor Mark Ruffalo will be honored with the Big Fish Award for his efforts with the Water Defense organization.
