Binder Lake IA 05-NOD-1395
Adams County S25T72NR34W 1 mile NE of Corning.
The Class BLW use is assessed (monitored) as “fully supported” based on information provided by the IDNR Fisheries Bureau in 2012 regarding improvements in the lake’s water quality and fishery. All other designated uses are “not assessed.” Note: A TMDL for siltation at Binder Lake was prepared by IDNR and approved by EPA in 2001.

According to the DNR Fisheries Bureau, the years since the renovation have brought vastly improved water clarity, and the rooted plant community has expanded dramatically. Prior to the renovation, the lake had small areas of lotus and curly-leaf pondweed present. Since the renovation, both plant species have expanded at least 10-fold in coverage area. The curly leaf coverage could be as much as 30% of the lake’s surface during its peak. Very little free-floating algae is present. Fish growth is normal or faster than most other southern Iowa lakes. Water clarity no longer suppresses the sport-fish population of Binder Lake. The DNR Fisheries Bureau anticipates that, as long as common carp can be prevented from re-entering the lake, the sport fish populations and water quality conditions will remain good. Based on this information in 2012 and the improvements in water quality conditions and sport fish populations, the assessment of the Class BLW uses of Binder Lake are assessed as “fully supporting.” See previous assessment for more information https://programs.iowadnr.gov/adbnet/Segments/1395/Assessment/2018
