Data on changing hydrogeomorphic characteristics along river gradients from nontidal through tidal freshwater to oligohaline reaches along the Mattaponi and Pamunkey Rivers, Virginia. Shapefile data include location and elevation profiles of the river valleys along multiple digital cross-sections from lidar digital elevation models, satellite visible imagery, and geographic information system analysis. These data were used to help interpret fundamental changes in regime along rivers as they transition from watersheds into the coastal zone.

The South Atlantic Conservation Blueprint is a living spatial plan to conserve natural and cultural resources for future generations. It identifies shared conservation priorities across the South Atlantic region. The second iteration of the Blueprint, Version 2.0, was released in July 2015. It was a completely data-driven plan based on ecosystem indicator models for terrestrial, freshwater, and marine environments, as well as a connectivity analysis. Blueprint 2.0 used a 200 m spatial scale. With Version 2.0, the total number of people actively involved in developing the Blueprint grew to more than 400 individuals from over 100 organizations.

From 16 June to 30 July, 2021, a Virginia Tech team of 4-6 sampled the fish community in 30 Shenandoah Valley streams (Virginia and West Virginia, USA) as part of a larger stream-health study including other teams who surveyed geomorphology, water quality, flow, temperature, macroinvertebrates, and fish health at the same 30 streams. The fish community team also sampled three additional bonus streams (SiteID's FOLL, NAKE, and TUMB) during 19-22 August, 2021. These 33 streams had upstream drainage areas of 7 to 46 sq. km and included 4 James River tributaries (SiteID's POAG, MLRB, CEDR, PISG), one Potomac River tributary (HARL), and 28 Shenandoah River tributaries. At each stream, we sampled fish from two reaches...

Over the summer of 2020, the Illinois Waterway (IWW) was closed to complete maintenance on lock chambers along the Illinois River. This closure restricted vessel traffic along the river and potentially changed habitat characteristics for aquatic vegetation establishment and growth. To assess if patterns of vegetation establishment and growth changed during the closure, peak biomass imagery from 2019 (pre closure) and 2021 (post closure) were compared for a vegetation response. This assessment found locations where aquatic vegetation increased and locations where aquatic vegetation decreased.

Ecosystems benefit people in many ways, but these contributions do not appear in traditional national or corporate accounts so are often left out of policy- and decision-making. Ecosystem accounts, as formalized by the System of Environmental-Economic Accounting Experimental Ecosystem Accounts (SEEA EEA), track the extent and condition of ecosystem assets and the flows of ecosystem services they provide to people...
Field data for vertical profiles of light and water quality parameters were collected biweekly between May and November in 2019 and June and October in 2020 in association with continuous monitoring platforms in Owasco, Seneca, and Skaneateles Lakes, Finger Lakes Region, New York. Water quality profiles were collected using Yellow Spring Instruments (YSI) EXO2 sondes and light profiles were collected using a LI-COR Photosynthetically Active Radiation (PAR) sensor in 2019 and Onset HOBO Pendant Temperature and Light data loggers in 2020. This data release includes all measured environmental parameters included in the analysis. This data release was produced in compliance with the open data requirements as a way...

Historic wetland footprints produced by combining National Wetland Inventory (NWI, 2009 updated), NRCS hydric soils data, and contemporary field surveys. These historic footprints provide the basis for restoration implementation within the Rainwater Basin Wetland Complex. This data was revised in 2016, succeeding the 2004 version. The 2016 revisions included eliminating historic wetland survey data, replacing NWI with the 2009 updated data, and inclusion of Olbut soils as a hydric soil class.

The data being released were part of a project funded by the United States Environmental Protection Agency (USEPA). This study sought to identify the planktonic communities (cyanobacteria, eukaryotic algae) potentially contributing to eutrophication within the Grand Calumet River Area of Concern (AOC) in northern Indiana along the southern shore of Lake Michigan. In 2021, triplicate water samples were collected from five locations during three events, 4/19/21 and 4/20/21, 7/7/21, and 9/15/21. Water samples were processed and planktonic communities were determined by a DNA-based technology (algal metabarcoding). Sampling locations: 1. Columbia Avenue, Hammond, IN 2. Lake George drainage ditch, Hammond, IN 3. Indiana...

This dataset contains modeled daily lake area, volume, constituent mass, and biogeochemical rates for 3,692 lakes in the Northern Highlands Lake District (NHLD) for one retrospective model run (1986-2010) and 12 model runs under future climate scenarios. This dataset was created using published tools developed to simulate detailed hydrological and biogeochemical fluxes for thousands of lakes and reservoirs over large spatiotemporal scales. The lake hydrology model utilized a computationally-efficient integrated surface water and groundwater modeling framework that informed a lake water budget model incorporating daily hydrologic inputs and exports from individual lakes within the modeling domain. The lake biogeochemical...
High gradient streams and rivers of the Ozark Highlands were selected by the Gulf Coastal Plains and Ozarks (GCPO) Adaptation Science Management Team (ASMT) as a priority habitat system. The goal of this document discover and apply geospatial data and analysis to estimate the amount, configuration and condition of key habitat features of high gradient streams and rivers of the GCPO. The desired ecological state for priority habitat systems should characterize the least impacted condition – systems in this condition should be targets for maintenance/protection and the goal of restoration activities in degraded systems. In the GCPO Integrated Science Agenda (ISA), a general description of the desired ecological...
Small, surface-release dams are ubiquitous across the U.S. and have the potential to alter stream flow, impede sediment and nutrient transport, and fragment biotic assemblages. To mitigate these and other ecological impacts and reduce public safety hazards, dam removal has become an increasingly prevalent method of stream restoration. However, few streams have been consistently monitored before and after dam removal, and there is a need for more information regarding how dam removals affect stream ecosystems across different dam, stream, and watershed characteristics. The presented data aimed to quantify the effects of dams and dam removals on two critical water quality parameters (stream temperature and dissolved...

Small, surface-release dams can impair natural stream connectivity by disrupting the flow of water, sediment, nutrients, and biota. Many dams built during the 19th and 20th centuries have exceeded their functional lifespan, and as a result, dam removal has become an increasingly prevalent stream restoration method. However, many streams have not been consistently monitored before and after dam removal, and there is a paucity of information regarding how dam removals affect stream ecosystems across different dam, stream, and landscape characteristics. Therefore, this study aimed to quantify the effects of dams and dam removals on a critical water quality parameter (stream temperature) across 16 Massachusetts streams...
