Description: This is a draft set of centroids of the impaired wetlands as determined by MPCA's surface water quality assessment process in 2012 and 2013 for the 2014 reporting cycle to US Environmental Protection Agency (EPA). Wetlands declared impaired prior to 2012 are also included in this dataset unless they have been delisted. Impairments on waterbodies included in the dataset were approved by EPA on May 29th, 2018. The wetlands these points are based on are a subset and enhancement of the 1:24,000 scale National Hydrography Dataset (NHD). In cases where the NHD does not include wetlands that MPCA has assessed, additional wetlands from the MN Department of Natural Resources (DNR) Division of Waters lakes database are added. Since the impaired wetlands are a small subset of the NHD and DNR waterbodies, only that subset is included in the dataset. This dataset includes impaired wetlands which have not yet had a TMDL plan approved by the US EPA.
Description: This is a draft set of centroids of the impaired lakes as determined by MPCA's surface water quality assessment process in 2012 and 2013 for the 2014 reporting cycle to US Environmental Protection Agency (EPA). Lakes declared impaired prior to 2012 are also included in this dataset unless they have been delisted. The waterbodies included in the dataset were approved by EPA on May 29th, 2018. These lakes are a subset and enhancement of the 1:24,000 scale National Hydrography Dataset (NHD). In cases where the NHD does not include lakes that MPCA has assessed, additional lakes from the MN Department of Natural Resources (DNR) Division of Waters lakes database are added. Since the impaired lakes are a small subset of the NHD and DNR lakes, only that subset is included in the dataset. This dataset includes impaired lakes which have not yet had a TMDL plan approved by the US EPA, those that have a US EPA approved TMDL plan as well as those lakes that do not need a TMDL plan.
Description: This is a draft set of the impaired streams as determined by MPCA's surface water quality assessment process in 2012 and 2013 for the 2014 reporting cycle to US Environmental Protection Agency (EPA). Streams declared impaired prior to 2012 are also included in this dataset unless they have been delisted. Impairments on waterbodies included in the dataset were approved by EPA on May 29th, 2018. These streams are a subset and enhancement of the 1:24,000 scale National Hydrography Dataset (NHD). In cases where the NHD does not include a stream reach that MPCA has assessed, a feature is added by MPCA. Since the impaired streams are a small subset of the NHD, only that subset is included in the dataset. This dataset includes impaired streams which have not yet had a TMDL plan approved by the US EPA, those that have a US EPA approved TMDL plan as well as those waters that do not need a TMDL plan.
Description: This is a set of the impaired beaches as determined by MPCA's surface water quality assessment process in 2012 and 2013 for the 2014 reporting cycle to US Environmental Protection Agency (EPA). The impairments on beaches included in the dataset were approved by EPA on May 29th, 2018. These beaches are a subset and enhancement of the 1:24,000 scale National Hydrography Dataset (NHD). In cases where the NHD does not include a feature that MPCA has assessed, a feature is added by MPCA. Since the impaired beaches are a small subset of the NHD, only that subset is included in the dataset. This dataset includes impaired beaches that have not yet had a TMDL plan approved by the US EPA.
