New Findings Show Poplar River Sediment Reduced by 35%
Lutsen, MN – The Minnesota Pollution Control Agency (MPCA) provided updated data trends on sediment in the Poplar River to the Poplar River Management Board in February. MPCA has estimated that total suspended solid (sediment) loads have been reduced by about 35% since 2006.
The sediment loads from 2002 to 2006 was about 1,000 tons per year, while the average load for the years 2009 through 2011 was about 660 tons per year.
Tom Rider, President of the Poplar River Management Board said the report was good news. “We have worked since 2005 identifying the most significant sources of sediment and implementing best management practices and conservation projects.”
The MPCA analysis suggests continued decrease in sediment loading should be expected from projects implemented in 2012 and planned for 2013. This includes the Ullr Tightline project that was completed in November of 2012 with estimated sediment reductions of 90 tons/year.
