Data Files for Peak-Flow Frequency Analyses for Selected Streamgages in North Dakota Based on Data Through Water Year 2022 (ver. 2.0, January 2026) Data Files for Peak-Flow Frequency Analyses for Selected Streamgages in North Dakota Based on Data Through Water Year 2022 (ver. 2.0, January 2026)
Data release contains peak-flow frequency analyses for selected streamgages in North Dakota, along with information documenting the input data and specifications for the analyses. The analyses were performed using the methods described by Siefken and others (2025). The analyses are presented by delineated basins in associated child items.

Data from a Nevada telemetry study extending 1997-2006 research on historical mercury contamination on snowy egrets (Egretta thula) up to ~ 20 days of age.
eDNA and visual encounter survey detection of amphibians and chytrid fungus in Colorado canyonlands, 2019-2022 (ver. 1.1, November 2025) eDNA and visual encounter survey detection of amphibians and chytrid fungus in Colorado canyonlands, 2019-2022 (ver. 1.1, November 2025)
This dataset contains environmental DNA (eDNA) and visual encounter survey (VES) data collected between 2019 and 2022 in Colorado canyonlands. eDNA data (field, extraction, and qPCR) is for three target species: American bullfrog, northern leopard frog, and Great Basin spadefoot. VES data is for six target species: American bullfrog, northern leopard frog, Great Basin spadefoot, red...
Ocular field estimates of exotic annual and perennial grass cover across the Soda Wildfire Ocular field estimates of exotic annual and perennial grass cover across the Soda Wildfire
Data includes functional group cover of exotic annual grasses and deep rooted perennial grasses within the first five years after the 2015 Soda wildfire across different post-fire restoration treatments. Additional landscape and restoration treatment covariates hypothesized to influence post-fire invasive annual grass and perennial grass cover are included.
