The lifespan of a typical reservoir can vary widely depending on factors such as construction quality, maintenance, and environmental conditions. In general, well-designed and properly maintained reservoirs can have a lifespan of several decades to over a century. Some reservoirs may need periodic upgrades or rehabilitation to extend their usefulness.
Over time, sedimentation and changes in environmental regulations can also affect the lifespan of a reservoir. Advanced techniques such as desilting and sediment management can help prolong a reservoir's life. Ultimately, the longevity of a reservoir is influenced by the balance between its ongoing maintenance and the natural processes that may reduce its storage capacity.
