Abstract for the dataset - This dataset accompanies the manuscript Unintended consequences of selective water withdrawals from reservoirs alter downstream macroinvertebrate communities in Water Resources Research [DOI]. Benthic macroinvertebrates were collected from samples taken annually during the first two weeks of August from 2002-2007 and again in 2017 at six sites in the South Fork McKenzie River. Taxonomy of samples collected prior to 2017 have been updated to be consistent with 2017 taxa designations. 2. Context of the research project that this dataset was collected for. Additional contextual information is available in the relevant manuscript. 3. Date of data collection: During the first two weeks in August, 2002-2007, and 2017 4. Geographic location of data collection: Sites 1-3 were located above Cougar Dam on the South Fork McKenzie in the Willamette Basin, Oregon at river kilometer 20.1, 18.5, and 16.9, respectively. Sites 4-6 were located below the dam at river kilometer 6.4, 4.8, and 3.2. 5. Funding sources that supported the collection of the data: US Army Corps of Engineers, US Forest Service Pacific Northwest Research Station, and Oregon State University provided funding and support during this research. Accompanying analyses were also supported by the James Sedell Graduate Scholarship to Christina Murphy. -------------------------- SHARING/ACCESS INFORMATION -------------------------- 1.

Dataset Digital Object Identifier (DOI) https://doi.org/10.7267/k3569b941 -------------------------- VERSIONING AND PROVENANCE -------------------------- 1. Last modification date 2020-01-10 2. Was data derived from another source? Data were merged from individual files and combined with trait database categories as described in Poff et al. (2006). The absence of flight sub-category was identical to the absence of emergence sub-category, so only absence of flight is included here. We populated the full trait database for the taxa here using Poff et al. 2006, Gerth et al. 2013, and our professional judgement. -------------------------- METHODOLOGICAL INFORMATION -------------------------- As described in "Unintended consequences of selective water withdrawals from reservoirs alter downstream macroinvertebrate communities". --------------------- DATA & FILE OVERVIEW --------------------- 1.

Number of variables:74 2. Number of cases/rows: 1,925 3. Missing data codes: NA Not applicable 4. Variable List Example. Name: Species Description: Species of the Drosophila sampled DML = Drosophila melanogaster DMJ = Drosophila mojavensis O = Other A. Name: Taxon Description: Finest taxonomic resolution identified for associated data (e.g. species if identified) B. Name: Sample Description: [Site code]R (e.g. 01R), R signifies that sample was a 'riffle' sample as described in associated methods. C. Name: Year Description: Year of sample collection D. Name: CorrectionFactor Description: 1 if all individuals were counted, >1 if a sufficient number of individuals were counted by subsampling and a correction was applied to generate the abundance per m2 (DEQ Level 3 Stream Macroinvertebrate Protocol in the Water Quality Monitoring Guidebook - Version 2.0) E. Name: Abundance Description: Individuals of given taxon per m2 F. Name: Proportion Description: Individuals of given taxon divided by the total number of individuals from all taxa collected in that sample (Site_Year) G. Name: Site_Year Description: Combination of Sample and Year, each unique value indicates a unique sample H. Name: PHYLUM Description: Phylum of taxon I. Name: CLASS Description: Class of taxon J. Name: ORDER Description: Order of taxon K. Name: FAMILY Description: Family of taxon L. Name: subfamily Description: Subfamily of taxon (if applicable) M. Name: GENUS Description: Genus of taxon N. Name: Taxon_Group Description: Indicates the unique groups (usually genus level) used in analyses FOR O. through BV. below: 1 is yes, 0 is no, 0.5 if yes for some taxa in Taxon_Group; each category, such as voltinism, sums to 1 for each Taxon_group EXCEPTION sync_NA is identical to (and thus also represented by) flgt_NA and so has been removed.
