Environmental DNA and qPCR data for an algal bloom in Kabetogama Lake, northern Minnesota, 2021

This data release provides phytoplankton environmental DNA data and cyanotoxin gene qPCR data from an algal bloom at Ash River Boat Docks on Kabetogama Lake, Voyageurs National Park, Minnesota, USA (USGS site ID 482603092511801) collected in 2021 and analyzed by the commercial laboratory Jonah Ventures. We sampled cyanobacteria over a 24-hour period at Ash River Boat Docks in Kabetogama Lake, along with photosynthetically active radiation, to assess the relation between sunlight and these cyanobacteria. Sixteen environmental samples and three quality assurance replicates were collected from two sites, one at the end of the dock and one at the shoreline, between September 9, 2021 and September 10, 2021.
