Dolomedes tenebrosus
(Dark Fishing Spider)

I think it’s Dolomedes tenebrosus because of the orange leg band markings. The dot markings are on all of the American Dolomedes species more or less. They are particularly prominent on your spider. I used the photos on Bugguide to compare them. Our Dolomedes vitatus photos are a mess of species because the site programming treats the species names, like vitatus, like human surnames and clumps them together. I don’t know why we can’t get that changed. Nobody else has weighed in on this spider yet….anybody?…..
