The U.S. Forest Service and USDA’s Natural Resources Conservation Service are working together to improve the health of forests where public and private lands meet. Through the Joint Chiefs’ Landscape Restoration Partnership, the two USDA agencies are restoring landscapes, reducing wildfire threats to communities and landowners, protecting water quality and enhancing wildlife habitat.

Mississippi River Basin Gridded SSURGO Hydric Classification – Presence "hydclprs". An indication of the proportion of the map unit that is hydric, based on the hydric classification of individual map unit components.

The subset of all NRCS Common Resource Areas (CRA), version 1.2, that can support native prairie habitats within the Mississippi River Basin. A Common Resource Area is defined as a geographical area where resource concerns, problems, or treatment needs are similar. It is considered a subdivision of an existing Major Land Resource Area (MLRA) map delineation or polygon. Landscape conditions, soil, climate, human considerations, and other natural resource information are used to determine the geographic boundaries of a CRA.

In order to identify areas within the Mississipi River Basin (MRB) where implementing wildlife conservation actions could potentially provide the highest benefit to both local waters and the Gulf of Mexico the Miss. River Basin/Gulf Hypoxia Initiative identified a "Water Quality Priority Zone". This provisional zone of interest represents HUC-8 watersheds having the highest potential for nutrient export from agricultural sources (using nitrogen as a surrogate). The potential for nutrient export was determined using the 2002 SPARROW Mississippi/Atchafalaya River Basin Model and cropland data from the 2013 USDA-NASS Cropland Data Layer. As the results from the SPARROW model are somewhat dated (ca. 2002), we incorporated...

Nitrogen (N) and phosphorus (P)-related impaired waters for which a TMDL has been developed (Cycle Year 2010) within the Mississippi River Basin. For purposes of identifying N/P-related TMDLs, EPA used the following national impairment categories: algal growth, ammonia, noxious aquatic plants, nutrients, organic enrichment/oxygen depletion.

An interdisciplinary and multiagency study was undertaken to study harmful algal bloom (HAB) dynamics on the Caloosahatchee River, which drains to the west from Lake Okeechobee into the Gulf of Mexico. Algae and cyanobacteria play crucial roles in aquatic ecosystems, but under favorable environmental conditions certain taxa may experience population growth booms resulting in HABs. Four independent mesocosm experiments were conducted in September 2019, June 2020, September 2020, and February 2021 to capture natural temporal variability in water quality and phytoplankton assemblages. The experimental installation consisted of three floating metal cradles each containing four fiberglass chambers filled with native...

Pilot Basins are HU-4 basins where there is an alignment of ecological and production systems of interest with areas thought to be producing significant agricultural nutrient loads and possessing significant implementation interests. These provisional basins represent areas of greatest opportunity in terms of need and potential for conservation delivery. Two tiers of pilot basins were identified for version 1.02 of the Conservation Blueprint. Tier 1 pilot basins have the highest nutrient load potential and the highest amount of watershed implementation interest, while Tier 2 pilot basins have either lower load potential or lower watershed implementation interest than Tier 1 pilot basins. Implementation opportunities...

This U.S. Geological Survey (USGS) data release provides a comprehensive dataset of water-quality results, physical-parameter measurements, hydrologic measurements, and site information collected to study the nature and extent of water quality along groundwater flow paths adjacent to glacial-kettle lakes on Cape Cod, Massachusetts. Water-quality samples were collected in 2003, 2005, and 2012 through 2018 in and near seven kettle lakes located on western Cape Cod, with most of the data collected in 2015-2017 from Ashumet Pond, which is located in the towns of Falmouth and Mashpee. Data were also collected at other lakes to compare the lake-specific influences of geochemistry and hydrology on the downgradient groundwater...

A one-dimensional surface-water quality model of the central Salem River Basin, New Jersey was developed to examine the causes of eutrophication and predict the effects of reduced point and nonpoint source nutrient loads on water quality. The model was developed using the USEPA WASP code. The model simulates channel flow and the fate and transport of dissolved oxygen, oxygen demands, nutrients, and phytoplankton chlorophyll-a in the main stem river and largest tributary from April 1, 2007 to October 31, 2008. Continuous and discrete water-quality data from the Salem River were collected during this period to help build and calibrate the model. The calibrated model was used to evaluate the effects of (1) natural...
Most forests in North America remain nitrogen limited, although recent studies have identified forested areas that exhibit symptoms of N excess, analogous to overfertilization of arable land. Nitrogen excess in watersheds is detrimental because of disruptions in plant/soil nutrient relations, increased soil acidification and aluminum mobility, increased emissions of nitrogenous greenhouse gases from soil, reduced methane consumption in soil, decreased water quality, toxic effects on fresh-water biota, and eutrophication of coastal marine waters. Elevated nitrate (NO- 3) loss to groundwater or surface waters is the primary symptom of N excess. Additional symptoms include increasing N concentrations and higher N:nutrient...

Conservation Opportunity Areas (COA) are intended to guide conservation activities at a landscape level. Landscape conservation is a developing theme across the country and throughout Indiana. Building off the successes of other Indiana landscape initiatives, like Goose Pond Fish and Wildlife Area and the Healthy Rivers Initiative, Indiana DFW has identified opportunities on the landscape to focus conservation efforts over the next decade. These COA were identified as a way to direct actions toward specific areas on Indiana’s landscape.

The Gridded SSURGO National Commodity Crop Productivity Index (NCCPI), version 2.0, arrays soils according to their inherent capacity to produce dryland (nonirrigated) commodity crops. Most of the NCCPI criteria relate directly to the ability of soils, landscapes, and climates to foster crop productivity. A few criteria relate to factors that can limit use of the land (e.g., surface boulders). All criteria used in the index affect crop culture and production and are referred to as factors affecting inherent productivity. Higher values represent higher capacity for production. Extent: Mississippi River Basin. IN ORDER TO CREATE A MANAGEABLE FILE SIZE, THE ORGINAL DATA WAS MULTIPLIED BY 100, THUS VALUES RANGE FROM...

This dataset records Cladophora and associated benthic algae, collectively Cladophora community or submerged aquatic vegetation (SAV), biomass collected during the growing season of 2020 at stations located along the U.S. shoreline of Lakes Michigan, Huron, and Erie. It also records a variety of supporting data collected at Cladophora measurement stations. These supporting data include: - measurements of Secchi disk depth and water chemistry; - water column profiles of temperature, specific conductivity, turbidity, pH, phycocyanin, chlorophyll, and dissolved oxygen; - diver observations of SAV, dreissenid mussels, round goby abundance, and substrate properties; - measurements of dreissenid mussel abundance and size...
