Recently, pelicans have been congregating near the weir because fish cannot pass the structure and are trapped there. For the birds, it’s an “all you can eat buffet.” Modifying the weir will allow fish to easily move up and down the river, helping them to flourish, and a healthy fish population is also good for pelicans! After the weir’s reconstruction, rather than finding an unnatural concentration of pelicans in this small area, it is likely that the pelicans will disperse further up and down the river.
