Summary

Two unique datasets were gathered to document whether flow management for hydropower affects the abundance and diversity of aquatic insect assemblages. The first dataset was collected in Grand Canyon from 2012-2014 by citizen scientists rafting the Colorado River. Simple light traps were set out each night in camp and used to capture the adult life stages of aquatic insects that emerged from the Colorado River. Three aquatic insect taxa were captured in sufficient abundance to analyze statistically including midges (order Diptera, family Chironomidae), micro-caddisflies (order Trichoptera, family Hydroptilidae), and blackflies (order Diptera, family Simuliidae, principally Simulium arcticum). These data were used to identify whether [...]

Purpose

These data were collected to document whether flow management for hydropower production affects the abundance and diversity of aquatic insect assemblages in rivers. The purpose of these data is to identify how the abundance and diversity of aquatic insects in regulated rivers is affected by dam operations that maximize hydropower. The citizen science light trapping data from Grand Canyon were used to test predictions of a theoretical model regarding spatial variation in aquatic insect abundance along a river continuum. The regional analysis data also served as a test of our theoretical model and were used to evaluate whether insect diversity varies in response to the intensity of hydropower generation.
