Standardized monitoring is a vital component of fisheries assessment in Missouri River impoundments. In South Dakota, annual variation in fish growth and abundance is used to monitor changes in fish populations and develop strategies (i.e. regulations) for managing recreational fishes. Although variation in fish abundance provides important insight into the status of fish populations, it can be difficult to link these changes to environmental conditions (i.e. hydrology) without concurrent information about reservoir productivity. Measures of nutrient concentration, algal biomass, and zooplankton composition/abundance provide important insights into reservoir productivity, but standardized approaches for collecting these measures have not been developed for …
