π£ Utah wiped out fish in reservoir for a major comeback π£
In August 1990, Utah wildlife officials conducted a massive chemical fish removal at Strawberry Reservoir to save its ecosystem. This operation took place near Heber City, Utah, removing over 99 per cent of the lakeβs total fish biomass. The reservoir was struggling because non-native fish like Utah chub overwhelmed the native trout population. After the treatment, biologists restocked millions of native Bear Lake cutthroat trout to rebuild the food web. This led to annual catches exceeding 715,000 fish by the mid-1990s.
