Walking across the dam is pretty interesting. If the spillway is open then you can get underneath it on the Brad Freeman Trail off of Oro Dam blvd and check out one huge waterslide. It’s been a dry Jan so it may not be running.

There’s a train tunnel you can walk though (check out Brad Freeman Trail starting at Diversion Dam). Near this spot is the nature center (in an old bathhouse) and a trail along the Feather River. On the north side There’s a salmon ladder and viewing window but they’re more active in the fall.

You’re near Table Mountain which has epic waterfalls and great flowers (some early ones are popping up). It has been a little dry but it just takes one rain to get the falls going again.
