I see them pretty often in the summer and fall when fishing the tidal flux in some of the creeks/rivers entering Grays Harbor and Willapa Bay. I think they eat a lot of crawdads just above the head of tidewater.
Its kind of a drag when one of those little rascals gets territorial and huffy at you, won't leave the pool, but keeps swimming around scaring the cutthroat and wheezing at you. Re_e_e_e_al cute!
I usually see families with a mom and 4 or 5 pups early on, in June and July. This year there was one in the estuary just above the Elk River bridge.
Fresh/Salt? River Otter vs Sea Otter? There is no hard and fast boundary for these local river otters, as far as i can tell. They don't mind the salt, and are in the estuaries. Lakes, too.
I thought I saw some Sea Otters on a Cape Flattery beach several years ago. They looked bigger, though.
I see Mink in the Willapa River in the tide-affected water upstream of the Hwy 101 bridge all the time. Along the bank, on top of pilings, swimming across. Saw one come out of the water with a Peamouth Chub in its mouth on lower Smith Creek a few years ago, and run up a small downed tree trunk only about 30 feet away.
We have regular ol' weasels here at the beach in Westport. I used to see them at Westhaven State Park. I'll bet they ate a lot of pheasants. Maybe not. Maybe the pheasants ate the weasels. I always saw more pheasants there then weasels.:beer2:
One mama weasel tried to raise a family under the water heater between the men's and women's restrooms in the OLD Westhaven St Park bathhouse back in the early 80's, but thats ancient history. The shoreline has long since eroded eastward of the old bathhouse, the area filled in, and a new bathhouse built. However, I saved a corner chunk of the old bathhouse to use as a doorstop.
Well, they ripped up the area to build a golf course, and then the developer ran out of money. I hope the original weasels do better.
Don't worry about those river otters eating too many cutthroat, though. They were here eating them long before WE took the fish populations down.
