PIT Tags Encountered by Klamath Falls Field Station Equipment in the Upper Klamath Basin 1993-2023 (ver. 2.0, August 2023) PIT Tags Encountered by Klamath Falls Field Station Equipment in the Upper Klamath Basin 1993-2023 (ver. 2.0, August 2023)
Data were collected as part of a long-term capture-recapture program to assess the status and dynamics of populations of two long-lived, federally endangered catostomids in Upper Klamath Lake, Oregon and Clear Lake Reservoir, California. Lost River suckers (LRS; Deltistes luxatus) and shortnose suckers (SNS; Chasmistes brevirostris) have been captured and tagged with passive integrated...
U.S. Geological Survey Precipitation Chemistry Quality Assurance Project Data 2021 – 2022 U.S. Geological Survey Precipitation Chemistry Quality Assurance Project Data 2021 – 2022
The National Atmospheric Deposition Program/National Trends Network (NADP/NTN) was initiated in 1978 by the Association of State Agricultural Experiment Stations to monitor long-term atmospheric chemistry and the effects pollutants have on aquatic and terrestrial systems. As of fall 2023, precipitation was being collected at approximately 260 NTN sites in the United States, including...
