Abstract

The Marmot Dam, located on the Sandy River, Oregon, was one of the largest US dams to be removed. In this paper, the AA. report on the soil development of dewatered reservoir sediments, determined using a ripening index and assessing relative changes in sediment properties with depth in comparison to properties of downstream soils that were not inundated by the dam. The results indicate that chemical and biological ripening happen more slowly than physical ripening. As such, dewatered reservoir sediments likely reach field capacity before other crucial edaphic conditions have developed, such as the accumulation of plant-available iron and nitrate. This difference will greatly affect vegetation successional pathways in these newly created upland environments
