The floods have caused a decline in fish and mussel populations in affected areas, with some species struggling to recover. For example, fish counts in the Pedernales River dropped from 600–1,000 per hour to just 250–300. Mussels, which play a vital role in water filtration, have been particularly vulnerable to sediment displacement. These changes could affect water quality and the overall health of the ecosystem. However, resilient species like Guadalupe bass are adapting better, highlighting the varied impact of the floods. The long-term effects on aquatic life and water quality remain uncertain, emphasizing the need for continued monitoring.
