BROOKINGS, S.D. (KELO.com) — Freshwater mussels play a unique role in South Dakota rivers and streams as filters of contaminants but also as an indicator of waterway health and cleanliness.
A recent survey found that many species of these critical members of freshwater ecosystems may be vanishing within South Dakota. Recent surveys of the state’s 14 major river basins found only 17 of the 36 species once known to live in state waters, a 53% decline over prior surveys.
The decline in mussel populations is a major concern for those who seek to protect and enhance water quality in South Dakota. But populations are falling in many waterways that face pollution from cities, industry and agricultural runoff.
In the latest article published by South Dakota News Watch, available at the link here, freelance reporter Julie Bolding provides insight into why freshwater mussels are in decline and what it means to the South Dakota environment.
