A family out for a walk at the lake noticed the animal swimming, and today our cameras captured it cornered near a construction site at the lake.
The beaver has been spotted in the water near the existing dam at Tempe Town Lake, minding his own business.
"I thought it was a small dog, but then it got up into a shallow area we could see its tail and realized that it was a beaver," said Jane Ippolito.
Beavers are rare but have come to Tempe Town Lake before, but this time it is in a major construction zone where crews are building the new Tempe Town Lake dam. "There's a construction site right next to it full of things are probably dangerous, it looks like there's litter in the canal, and he needs to be moved somewhere else," she said.
Her family called Arizona Game and Fish. "They are native to this area and the Salt River, he was probably exploring the river and got into an area that is probably not a good habitat for him," said Amy Burnett.
Game and Fish came out, but it was too dark to see the beaver. It is possible he could leave on his own. "It's amazing the areas beavers can get out of they are good at navigating rivers and waterways, so he may not be in fact trapped, we'll have to assess the situation in the morning and find out if he needs to be rescued or if he can find his way down or up river," said Burnett.
If he needs to be moved, Southwest Wildlife will move the beaver to a safer location away from the construction equipment.
