流域的几乎所有部分都存在湖泊、水库和池塘，并保存了细颗粒物质通过沉积物梯级运动的不同时间尺度的记录。过去三十年中发生的一些进展改进了这些沉积盆地内记录的收集、年代测定、分析和解释方法。结合其他来源的地貌、考古和历史数据，基于湖泊和水库沉积物的古环境重建所提供的信息为加速或减少侵蚀率的因素提供了重要的见解。随着湖泊沉积物分析被纳入更广泛的流域规模侵蚀和沉积物输送研究中，作为旨在将当代过程研究置于历史背景下并探索不同时间尺度沉积物输送过程控制的总体战略的一部分，从这些沉积物汇中获得的信息的价值不断增加。
Lakes, reservoirs and ponds exist in almost all parts of the drainage basin and preserve records over varying timescales of the movement of fine particulate material through the sediment cascade. Several developments have taken place over the past three decades that have produced improved methods for the collection, dating, analysis and interpretation of the records contained within these sedimentary basins. Coupled with other sources of geomorphological, archaeological and historical data the information provided by palaeoenvironmental reconstruction based on lake and reservoir sediments provides important insights into the factors that accelerate or reduce erosion rates. The value of information derived from these sediment sinks increases as the analysis of lake sediments is incorporated into broader studies of erosion and sediment transport at the catchment scale as part of an overall strategy aimed at placing contemporary process studies in a historical context and in exploring controls on the sediment delivery process at different timescales.
