Maquoketa River moving massive amounts of sediment

DELAWARE COUNTY (KWWL) -- Without the Lake Delhi dam to stop it, the Maquoketa River is now moving 80 years of accumulated silt downstream.

Experts with the Natural Resources Conservation Service in Iowa say Lake Delhi acted as a sediment trap for all those years. Now, the river is moving all that away, and it's collecting in streambeds and fisheries elsewhere.

Experts also say major flooding in the future could mean the sloughing of channels.

Long-term options to fix this problem include reinforcing the current river's walls and rebuilding the dam. Short-term options include spreading oats over the exposed lake bed in order to help stabilize the erosion.

Watch KWWL and follow to learn more about proposed solutions and the impact the sediment-washing is having on the environment.
