(KCCR) — Officials with the South Dakota Game, Fish and Parks Department will be holding meetings this week to address the recent discovery of invasive zebra mussels in Lake Sharpe. Two sets of meeting will take place tonight and Thursday. Tonight the meeting will be held at the Arrowwood Resort in Oacoma and Thursday at the Ramkota in Pierre. Both meetings will be held from approximately seven to nine to pm. The meetings will provide information on reducing the risk of spreading zebra mussels and examples of how zebra mussels have been mitigated and controlled especially with underwater infrastructure. Zebra mussels have the biggest impact on things like municipal water system intakes, hydropower equipment, irrigators, industrial users and rural water systems. Mussels can clog water intakes and pumps, restricting water flow. The cost of mitigating mussel impacts can be millions of dollars annually for surface water users.
