The Bureau of Reclamation has launched a new prize competition seeking innovative solutions for the 100-percent eradication of invasive quagga and zebra mussels from large reservoirs, lakes and rivers in a cost-effective and environmentally sound manner. Invasive mussel infestations pose significant logistical and economic challenges for local communities, recreationists, and water managers by potentially disrupting water deliveries, increasing facility maintenance cost, and impacting the local ecology.
