Not my usual territory - I'm more shadow people and NDE research - but this caught my eye because a mate of mine drove through that region in July and mentioned something similar without me even prompting him. Big canine, upright or near-upright, crossing a road near the riverbank at dusk. He's not into any of this, which is kind of why I noted it down.
What's the current sighting distribution looking like along the river? I'd want to see whether theres any clustering around specific terrain features before drawing any conclusions. Bridges, tributary confluences, that sort of thing. In my experience with paranormal photography you start to notice that genuinely unusual phenomena tend to repeat in geographically logical ways, not randomly scattered.
Anyone actually managed to get footage or even decent stills? That'd be the deciding factor for me. Eyewitness accounts alone aren't going to move the needle much given how unreliable human perception is at dusk.
