Mowry Canal
In Biscayne NP, we paddled up this canal that flowed into the bay. The ranger is in the canoe ahead and just over his head you can see the gates used to control flow of fresh water into the bay. There are a bunch of these canals and, while probably necessary to provide fresh water for the population (which grows by 800 per day), it wreaks havoc on the marine life used to steady salinity levels. The canoe trip was fun but, as you can see, overcast with a little rain.
