About a year ago I saw three what looked like river otters swimming around some rocks in the river end of Bartlett lake. They appeared to be the size of a house cat. I talked to AZ Game and Fish and they thought they were Muskrats. They said AZ used to have river otters but they were trapped so heavly that there are now few left. I wasnt able to get a close up view but did notice a bobcat approached them (I assume to take their meal) These things wouldnt back down for nothing. They ended up chasing the bobcat away. Two weeks ago I spotted them again swimming around just past the no wake bouyies. I was a little closer and observed one crawl out of the water on to the rocks. It was a little larger then a adult house cat and was dark brown in color. Just wondering if anyone else had seen these up in that area? They sure were fun to watch. As a side note they used to be two bald eagles which flew around in the same area. I havent seen them in a while and am wondering if they left for a better habitat.
