From 2 April - 29 April 2022, a Virginia Tech team of 2-3 sampled the macroinvertebrate community in 30 Coastal Plain streams (Delaware, Maryland and Virginia, USA) as part of a larger stream-health study including other teams who surveyed geomorphology, water quality, flow, temperature,fish community, and fish health at the same 30 streams. Macroinvertebrates were sampled using a 250 micrometer mesh slack sampler on a known area. At each stream, samples were collected in two ways. 1) Five slack samples were taken in riffles according to the USGS National Water-Quality Assessment protocol, and 2) Five additional slack samples were collected in the most productive available habitat types such as woody debris, undercut...
As part of a larger study examining stream conditions and the effect of Best Management Practices in the Chesapeake Bay watershed, thirty small streams on the Delmarva Peninsula were instrumented and monitored for gage height (water level), water temperature, and air temperature using Onset HOBO sensors from March to September 2022. In addition, two discrete discharge measurements were made at baseflow at each site. This data release contains four .csv files with time-series for gage height, water temperature, and air temperature for all thirty monitoring locations and a table of discrete discharge measurements and associated field measurement metadata: Delmarva_2022_Continuous_Air_Temperature.csv Delmarva_2022_Continuous_Gage_Height.csv...
From 31 May to 29 June, 2022, a Virginia Tech team of 4-5 sampled the fish community in 30 Delmarva Peninsula streams (Maryland and Delaware, 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. These 30 Chesapeake Bay Watershed tributaries had upstream drainage areas of 9 to 54 sq. km. At each stream, we sampled fish from two reaches using two-pass backpack electrofishing and seining. Reach A was the main reach surveyed by all the interdisciplinary teams; Reach B was surveyed for fish communities only. Reach length was 20 wetted channel widths, capped at 150 meters. Fish were identified...

U. S. Geological Survey (USGS) scientists completed a data collection campaign from the 25th of April to the 10th of June in 2022, using various methods to record geomorphic and habitat indicators throughout 30 streams on the Delmarva Peninsula. Field methods included GNSS surveys, gravelometer-based pebble count readings, visual assessments, and riparian analyses. This metadata record contains all raw observations from the campaign as well as numerous summary metrics to be used in model development. Those "model-ready" data can be found in Delmarva_Model_Deliverable.csv in the parent item, while the two child items containing raw in-channel observations and raw survey data. Attached to this release is a data dictionary...
