Just a word of caution on burning bottomland hardwoods, depending on species composition and objectives, you may end up damaging and losing a substantial amount of mature trees. Not saying you will here, as that fire looks low intensity, but Iβve seen bottomland hardwood burns result in a lot of mortality to red and white oaks, especially the water/willow component.
Go forth and prosper!

This late in the year and with any significant fuel load is gonna result in some damage and mortality.
White oaks, red oaks & poplar will be impacted the most.
