Wetlands provide numerous critical functions, including nutrition cycling and water quality improvement, that have made them a critical component of many state and local stewardship programs. Quantifying landscape nutrients entering wetlands are crucial components of state-led efforts to improve nutrient reduction strategies, both for water quality within wetlands themselves and for other water sources, such as lakes and streams, that wetlands provide a buffer for nutrient inputs. However, these data are rarely assembled at comprehensive scales that are relevant to management, such as local wetland basins, stream catchments, watersheds. This subproduct provides downscaled data from EPA's National Nutrient Inventory (NNI; https://www.epa.gov/water-research/national-nutrient-inventory-portfolio) for approximately 84 million individual wetland basins over a 30-yr period accumulated for individual wetland basins, local stream catchments and full accumulative watersheds across the conterminous US. We generated annual landscape nutrient inputs from several anthropogenic sources across nearly 12 million wetland basins at 5-yr increments from 1987-2017 (1987, 1992, 1997, 2002, 2007, 2012, 2017), resulting in a novel and robust resource to explore effects of nutrient inputs on wetlands and the effect of wetland interception of landscape nutrients on other water resources. The new metrics cover all major anthropogenic sources of urban and agricultural nutrient inputs, including nitrogen metrics from livestock manure excretion, crop removal, and fertilizer. The accessibility of these data will greatly advance the way state partners generate nutrient budgets for impaired waters and conduct conservation and restoration planning to meet statutory requirements under the Clean Water Act.

This data release contains the R source code, inputs, and selected outputs associated with the turbidity-based regression models used to estimate total phosphorus concentrations and loads for the Missouri River at St. Joseph and Hermann, Missouri, for water years 2008–22. Additionally, the R source code, inputs, and selected outputs for LOADEST models used to estimate daily total phosphorus loads for the study period are included, as these loads were used for days when turbidity data was unavailable.

This tabular data set contains estimates of total phosphorus concentration and mass, as well as measurements of water discharge and volume at a diked wetland pool (Pool 2B) that was reconnected to a Lake Erie tributary (Crane Creek) via a water control structure in March 2011. Sampling occurred during 2013 and 2014. In addition, this data set contains evaluations of movement of total phosphorus and water through the reconnecting structure, frequency of changes in flow direction through the reconnecting structure, and dissolved oxygen measurements in the reconnected wetland pool.

This dataset represents wetland CEFs identified during the development review process since 1995. Prior to 1995, data is either unavailable or lost.Wetland CEFs were digitized from construction plans, environmental assessments, and City of Austin staff field observations. Features were digitized into a versioned SDE database in ArcMap. Wetland delineation may be determined through a process of negotiation with land development interests and generally reflect the most protective arrangement that could be obtained. Additionally, “fringe wetlands” were drawn using a standard 2’ width on either side of a waterway.
