The Tenneth River is huge and full of alluvium, making it's sediment extremely fertile. From the river, the people of the Tentran Kingdom have created irrigation channels, both to stop flooding and to also carry good water to their plants during times of little rain without having to work too hard. These channels are instrumental in Tentran's survival as a farming community, so they are well taken care of and being a person who cleans and creates them is revered in the Kingdom.
