What happened
The issues stem from the great dam and hydroelectric powerhouse at Keokuk, which began impounding the Mississippi River in 1913. Researchers studying Pool 19 documented that in 66 years, approximately 5% of the original volume of the pool had been filled with sediment. The Mayor of Hamilton, Illinois, stated that public access to Pool 19 at Chaney Creek is silted in and unusable.
Why it matters
The ongoing sedimentation is causing a significant reduction in the riverbed access and navigability of the Mississippi River. This siltation impacts the operational capacity of the waterway, which is vital for commerce and regional infrastructure.
