Springbank proposed dry dam

What are the environmental and watershed impacts of dry dams?

       "Given the design of dry dams as a short-term retention area for excess water, this inundation can lead to the loss of vegetation, forests and natural areas. To prevent adverse impacts to the local environment and biodiversity, dry dams should be built to accommodate both regular and rare floods, which require large storage capacity. The local watershed can also be impacted due to interruption of the sediment transport process. River flows carry sediment downstream for aquatic species and erosion prevention. Interrupting this process can cause turbidity issues downstream and soil erosion on riverbanks."
