In a 1982 US reservoir review, fish and plankton productivity rose after valleys were flooded, then declined as spawning habitat and detritus became less available

Following the creation of American reservoirs, there’s an initial surge in fish populations, creating a thriving aquatic ecosystem. However, as time passes, diminishing habitats and dwindling food sources lead to a decline in biomass. Recent research affirms this non-linear trend, prompting fishery managers to deploy ongoing interventions to maintain these artificially created lake environments.
