OVERVIEW

Description/Abstract

TROUT CREEK
Trout Creek Abstract: Data collected from three beaver-mediated reaches on Trout Creek during the summer 2022 field season.

Data includes variables for 36 beaver ponds, including location, pond geometry, pond classification, sediment, organic carbon, and water storage, and stable isotopes, collected to calculate volumes and rates of sediment and organic carbon storage in beaver ponds. Data also include radioisotopic activity concentrations for 5 beaver ponds older than 10 years for specific depth intervals within sediment cores and suspended sediment samples. Channel geometry metrics are also included, collected to characterize the degree of incision, connectivity, and ongoing erosion in each reach. Finally, metrics used to model and estimate rates of beaver-assisted channel infill via Monte Carlo simulations are included, such as the fraction of time in which specific beaver ponds were inundated over a 13-year period, and the longevity of ponds along Trout Creek.

DATASHEET DESCRIPTION:
Pond surveys: Within this folder, the “Pond survey metrics” sheets include geometric, age, sediment, water, and organic carbon storage metrics for each surveyed beaver pond. The “Survey sample points” sheets include measurements of sediment and water depth, as well as unique characteristics, for each individual sample point taken within each beaver pond. Ponds can be joined/related via the “Pond” field. Reaches can be joined/related via the “Reach” field.

• STABLE ISOTOPES: Within this folder are results from sediment sample testing at CU’s Stable Isotope Lab, including fraction by mass of carbon, nitrogen, delta 13-C, and delta 15-N. Ponds can be joined/related via the “Pond” field. Reaches can be joined/related via the “Reach” field.

• RADIONUCLIDE DATA: Within this folder are activity concentrations of various radionuclides at various depths within sediment cores and suspended sediment (PS samples) taken from beaver ponds older than 10 years. Ponds can be joined/related via the “Pond” field. Reaches can be joined/related via the “Reach” field.

• GEOMORPHIC SURVEYS: Within this folder are GPS data (coordinates and elevation) for points taken along cross-sections via RTK GPS at Trout Creek, used to characterize channel and valley-bottom geometry. This includes GPS coordinates, elevation, and descriptions of the type of geomorphic unit underlying the GPS point. Reaches can be joined/related via the “Reach” field.

• CHANNEL INFILL MODELING: Within this folder are data including the fraction of time beaver ponds along Trout Creek were inundated during a 13 year period (2009-2023) as well as the longevities of ponds on Trout Creek. Note the “Pond_number” field values in these two datasets are unique to their respective spreadsheets and may not be used to join or relate to any other spreadsheets within the dataset (including each other).

COAL CREEK
Coal Creek Abstract: Data collected from three beaver-mediated reaches on Coal Creek during the summer 2022 field season.

Data includes variables for 9 beaver ponds, including location, pond geometry, pond classification, sediment, organic carbon, and water storage, and stable isotopes. Data also include radioisotopic activity concentrations for 3 beaver ponds older than 10 years for specific depth intervals within sediment cores and suspended sediment samples.
