September 17th – 6:00pm – 8:00pm – What a great beaver night. The whole family of six, were seen during the evening.  The first beaver to be seen was  coming up from below the secondary at 6:00pm.  Another two were seen at the secondary and one of those beavers climbed the wall by the dam to get to some brambles.   Three beavers (including the kit) were seen down by Ward Street.  They were filmed navigating the dry spot near Starbucks. During all this beaver activity, a Kingfisher was hunting and diving below the Marina Vista Bridge. HP, JR, CR

September 10th – 4:45am – An adult beaver was seen  coming down from the primary dam and a yearling  was seen coming  up from the  secondary dam early this morning. JR

September 5th – 6:30pm-7:00pm – The secondary and third dam were covered by the high tide we had last night . One beaver was seen down below the third dam swimming up creek. It  stopped around the third dam and hung out there. That was the only beaver seen during the short time down at the dams. JO

August 30th – 6:00pm – 8:00pm – Three  beavers were seen down by the secondary dam. The kit and another beaver were seen in another location.HP, JR, CR, LB

August 19th – 8:00pm – A beaver watcher was filming down near Ward Street and he happened to be filming the new kit. The kit was by himself. No wonder the kit was not seen down near the primary nor secondary dams earlier in the evening.  Two large beavers had been seen earlier near Ward Street and it was reported that they were still in the area. HP, JR, MS

August 19th – 6:30pm – 8:00pm – It was a very cold night and also a very slow night for sightings of beavers. One yearling came swimming down from the primary dam and because of the high tide, he didn’t spend any time at the secondary dam before swimming on down the creek towards the third dam.  After some time, another yearling came down from the primary dam and took some willow into one of the bank holes. He swam around for a while and then he also went down stream. HP, JR, CR, LB

August 9th – 6:30pm – 8:00pm – Five beavers were seen this evening and the kit came out at 7:30. The kit was seen taking a ride on mom’s back.  There was a Great Blue Heron sighted down the creek and also talked with a man who had watched a turtle the night before laying eggs. He was able to get a picture on his cell phone. HP, JR

August 8th – 6:30pm – 8:30pm – Four beavers were seen at various times and all coming down from the primary dam. Two beavers worked on the secondary dam by putting mud and sticks on just the right places. Never saw the kit. One very large beaver up on the primary dam and swimming in that area. CR, LB, JO

July 29th – 6:00pm – 8:00pm – It was a very busy beaver night as there seemed to be lots of dam repairing to do on the secondary. Beavers were seen mudding and filling in the break in the dam caused by the high tide. All the beavers were seen working including the new kit, who tried to look busy. HP, JR

July 13th – 6:00pm – It was a very busy beaver night down by the secondary dam site. Two adult beavers were seen along with the 3 yearlings and also the new kit was out with the family. HP, JR

July 4th – 7:00pm – Four beavers along with the new kit were seen down by the secondary dam. All the people walking over the bridge on their way to the fireworks didn’t seem to bother the beavers. HP, JR

July 1st – 7:00pm – 9:00pm -   The kit was seen out by the primary dam around 8:00pm.  Also seen was an otter around the secondary dam. HP, JR

  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!
