July 15th – 6:00pm – Very slow beaver sighting night. No sightings at the primary dam until later in the evening. Two beavers were seen down at the secondary dam. A nice couple from Germany were down at the secondary dam and were lucky to see the two beavers. They were on their last week of a three week vacation in the US and the Martinez beavers were one of their destinations. They had read about them on the internet in Germany. One of the beavers swam up to the primary dam and everyone went up that way and were actually able to see mom beaver and Jr. up close. The couple went away very happy as they had only seen beavers in a zoo. CR, LB

my boyfriend and i decided to take a valentine’s day adventure from san francisco despite the rain and got lucky. just as we were getting impatient, we saw a critter pop its head above the water andheadtothe dam! it was around 7:30-8pm, he or she hopped up on top of the dam andwassnackingonsomething. we tried to get a better look with a flashlight (not smart) and scared the beaver away, but after a short walk we checked back and were surprised to see two beavers! can’t wait to come back when the daylight hours are longer!
