Dragonfly Eye

July 21st I went with the family to visit the mighty Niagara River to see the falls. I was also hoping to do a little surveying while I was out. We had a great time exploring Goat Island, taking a voyage on the Maid of the Mist, and walking to the foot of the falls in the Cave of the Winds. I did not find one dragonfly though! I’ll admit I wasn’t preforming an extensive survey, but the whole day I did not see a single ode. I would assume that this is because the rapids are so violent. I also do not know what flies on other parts of the river. Has anyone done any surveying above or below the falls?
