2016 Assessment Summary - WINOFI - Waters In Need Of Further Investigation
The state list of waters in need of further investigation is required by Iowa's Credible Data Law and is
comprised of waters in category 3b of Iowa's Integrated Report. WINOFI waters are those where
limited information suggests, but does not conclusively demonstrate, a water quality impairment.
For purposes of Integrated Reporting to USEPA, Iowa DNR's 3b subcategory is considered part of overall IR Category 3:
"Not Assessed" due to insufficient information for determining whether any use is met.
