These plants are very simple, lacking an obvious stem or leaves, but consist of a small 'thalloid' or plate-like structure that floats on or just under the water surface, with or without simple rootlets Utica Marsh Annual Clean-Up, April 25th, 2009 We couldn't have asked for a better day. A huge turnout of volunters coupled with fabulous weather equaled a successful event. A HUGE thank you to everyone who helped to make this a very successful year!!! We had over 110 volunteers from the community! The fabulous weather added to the success of our clean up as we cleared A LOT of trash and tires out of the marsh (we actually overfilled the tire bin!). We also had generous donations from Bob's Auto Parts, Walmart, SUNYIT, and Waste Management! The above slideshow contains pictures from the 2009 cleanup.
