One of the prominent features in the Agusan River basin is the presence of the [[Agusan Marsh]] covering a total area of 19,197 hectares. The [[marsh]] serves a flood retention basin for the Agusan River, cutting the high discharge of water causing flash floods in the lower reaches of the river. Aside from that, the marsh harbors unique and pristine habitats like the [[sago]] and peat swamps forest and is a home to endangered and endemic flora and fauna. As a consequence, it was declared by former President [[Fidel V. Ramos]] as a [[wildlife sanctuary]] in 1996.<ref name="adb"/>▼

===Watershed===
The Agusan River basin is divided into three [[drainage basin|sub-basins]] on the basis of topographic features: the upper Agusan River basin, the middle Agusan River basin, and the lower Agusan River basin. The upper Agusan River basin is the section from its [[headwaters]] in the mountains of [[CompostelaDavao Valleyde Oro]] province to [[Santa Josefa, Agusan del Sur]] to [[Veruela, Agusan del Sur]], the middle Agusan River basin is the section of the river from [[Santa Josefa, Agusan del Sur|Sta.Santa Josefa]] to Amparo, [[Agusan del Sur]] while the lower Agusan River basin is from Amparo to its mouth at [[Butuan City]], [[Agusan del Norte]].
