About this file

Written by GovTribe AI · Jun 18, 2026

This file is a macroinvertebrate bioassessment dataset prepared by Aquatics Associates, Inc. for the USFS Rio Grande National Forest in February 2023. The spreadsheet contains detailed community metrics and taxonomic data from four sampling stations collected on August 12 and August 16, 2022. The data includes raw organism counts, corrected density calculations (organisms per square meter), and standardized metrics including diversity indices, Hilsenhoff Biotic Index (HBI), Biotic Condition Index (BCI), functional feeding groups, and the Colorado Macroinvertebrate Multimetric Index (CO-MMI) scores. The four stations represent different locations: Middle Fork Carnero Creek at Carnero Guard Station (WJR22-001, 335 organisms, CO-MMI 33.6), Archuleta Creek above Rio Chama confluence (WJR22-002, 139 organisms, CO-MMI 61.2), and two samples from Rio Chama above Archuleta Corral (WJR22-003 and WJR22-004, 995 and 1,675 organisms respectively, with CO-MMI scores of 75.3 and 77.3).

The dataset includes detailed taxonomic identification at the genus or species level for 34 taxa across multiple aquatic invertebrate groups including Ephemeroptera (mayflies), Plecoptera (stoneflies), Trichoptera (caddisflies), Diptera (true flies), Coleoptera (beetles), and other macroinvertebrates. Accompanying metadata sheets provide functional classifications (filterers, scrapers, predators, shredders), habit designations (clingers, sprawlers), tolerance values for metal and White River National Forest specific tolerances, and Chironomidae (midges) analysis. The raw data sheet documents subsampling methodologies and grid-picking protocols, with subsample corrections applied to WJR22-003 (multiplied by 3) and WJR22-004 (100% Left and Right examination with multiplication by 5) to standardize results from different collection intensities.
