Program Description

LRFEP limnologists monitor water quality and limnological parameters throughout the reservoir, including dissolved oxygen, temperature, total dissolved gas, and zooplankton populations. These parameters influence the abundance, growth, and survival of resident fishes. Zooplankton are the primary food available for age-0 fishes, as well as for many adult fishes (including Rainbow Trout and kokanee). Therefore, monitoring of zooplankton populations and diversity is important for maintenance of a successful fishery. Additionally, LRFEP limnologists are currently assessing the impacts of hydro-operations on Lake Roosevelt’s limnological parameters and also monitor for the introduction of nonnative quagga and zebra mussels.
