May 2nd – 6:00pm  – Wow, what an amazing beaver viewing night. First two beavers were seen swimming down from the primary dam site. These two seemed to be the same size which made us wonder which ones these were. Soon last years kit came out from around the bank area and spent some time near the secondary dam. Also he was seen doing some minor repairs. The secondary dam looks great. It wasn’t much longer before we spotted a very large beaver that must have been Dad. Mom was seen also. There was so much beaver activity going on that it was hard to figure out how many beavers were out.  It was determined that five beavers were seen. HP, JR, CR, JO, LB

April 28th – 7:00pm – Two beavers were seen at the primary dam and they continued on down to the secondary dam ,where they joined two other beavers. Four beavers were seen altogether which is great news. JO

February 1st – 4:00am – There was very good news this morning from a very early beaver watcher.  The kit was seen  working away on the secondary dam.  He was making many trips bringing stuff to put on the right of the dam. This is the first time the kit has been seen in quite some time. JR

January 31st – 4:45am – Two beavers were seen this morning.  One looked like the same one seen yesterday working on the right side of the secondary dam. He stopped to have a snack. The other  beaver was seen working very hard in the shadows on the left of the dam. JR

January 30th – 4:45am – One  very large beaver came up over the secondary carrying a stick, which he proceeded to position in the dam, then went on mudding.

November 24th – 5:00pm – The beavers had some special visitors tonight and they went home pleased as they were not disappointed.   Dad, Mom and the kit were out near the footbridge and secondary dam. It was nice to see the family down by the secondary again. HP, JR

November 15th – 5:00pm – Oh what a great beaver sighting evening. Two of the yearlings came swimming out from the bank holes at the secondary dam and forged around looking for food. They took some branches into their home in the bank. After some time, the kit came out. This was the first time he has been seen down at the secondary in many weeks. He has been spending his time up at Ward Street recently. It was great to see him back down in that area. Another very large beaver appeared and there was a discussion about if it was Dad or not. In all, four beavers were seen including the kit. A great night for beaver watchers. HP, JR, LB

  1. Stephen Stout Says: To Whom It May Concern,Thank you to each and every one of you that participated in any capacity to save the Beavers. I have worked and lived in Walnut Creek for many years. I never had a reason to visit Martinez other than business or visit a friend. This evening my wife went out with friends so I thought it would be fun to visit my friend Kevin Bacon who lives in Martinez. My daughters joined me on the outing. After eating at Burlington’s(spell?) we visited the beavers and met several very nice people. I wanted to take the time to thank you for affording my family and I the opportunity of seeing animals in the wild. My daughters were able to walk away with a touch of nature and an experience that will last a life time. What a nice town you have. Again, thank you.
  2. Monty Says: I’ve recently been called to jury duty in Martinez. Can’t wait because I’ll be real early and try to catch a glimpse of the little critters! What an amazing thing to see. Thanks for this site and all the information.Monty
  3. Jean Says: The whole family has been seen in the last few days by a very diligent lover and videographer of the beavers. I’m so happy I’m dancing in the streets!!

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!
