I have multiple videos of this family, but they are not in .mov format. There is a pair and at least one, possibly two kits. The pond is located east of the 4th hole on the China Creek Golf Course at Newcastle, adjacent to (immediately west) of Cougar Mountain Regional Wildland Park. The pond is a retention pond (not beaver-dammed!)
Lovely web spun horizontal just an inch above the water (see other photos)
