This isn't a Wolf Spider, it is too hairy. I looked at pictures of a Fishing Spider as well and it doesn't look to be one of those either. It's abdomen is too round to be a Fishing spider. I can't identify it well with the picture given. Sorry.
Any large non-orb weaving spider in your area is going to be either a wolf spider or a fishing/nursery web spider. Although your image is too dark to be certain of an i.d., the banding on the legs and its general posture appears more consistent with it being a fishing spider in the genus Dolomedes than it being a wolf spider. Also, the shape of the abdomen in itself is not a reliable identifier, as this will vary with the sex of the spider (males tend to be more slender than females), as well as how well-fed the spider is, and in the case of females, whether or not it is gravid.
