Summary

These data were compiled as part of a long-term (1964 - 2022) water quality monitoring program at Lake Powell. Objectives of our study were to release a consistent record of long-term water quality data. The 58-year limnology dataset captures some water quality parameters (temperature, salinity, major ions, total suspended solids) from reservoir filling to present day. It also contains a 38-year record of secchi depth, and a ~30-year record of nutrients, phytoplankton, and zooplankton assemblages. The data were collected from various sites within the Lake Powell reservoir and the Glen Canyon dam. Regular monthly sampling occurred at three sites near the dam and reservoir-wide sampling was generally conducted quarterly, or least annually, [...]

Purpose

The purpose of these data are to provide of a long-term record of water quality data at Lake Powell to the public. These data were created to monitor water quality at Lake Powell. These data can be used to both explore long-term trends in water quality at Lake Powell and to inform regional, continental and global scale limnology studies.
