A paddleboarder was "guided to her death" on an excursion that saw four people killed, a court has heard.
Paul O'Dwyer, 42, Andrea Powell, 41, Morgan Rogers, 24, and Nicola Wheatley, 40, drowned while paddleboarding in "extremely hazardous conditions" on the River Cleddau in Haverfordwest, Pembrokeshire, in October 2021.
Nerys Bethan Lloyd, 39, from Port Talbot, is the former owner of Salty Dog, the now-dissolved company that operated the tour, who is being sentenced over the deaths.
Lloyd pleaded guilty to manslaughter last month and it was revealed she did not have the correct qualifications to run the tour.
The group of seven participants and co-instructor Paul O'Dwyer set off after 09:00 on 30 October 2021.
Mark Watson KC, prosecuting, told the court there had been heavy rain in the days before and "the river was in flood conditions" with a "visibly strong current".
"Of the eight individuals who went over the weir that day only four survived," he said.
