Here is a release from South Dakota Game Fish and Parks in reference to the winter kill at the third street dam in Huron.
GFP can confirm there is a sizeable winterkill at Huron’s 3rd Street Rapids. Many factors may contribute to winterkill, some of which may include low water and lack of dissolved oxygen. Low oxygen levels may stress fish and over extended periods of time can cause mortality. Winterkills such as this can happen in lakes and streams when water levels are low and heavy snow prevents sunlight from reaching the water column.
Shortnose and longnose gar and silver and bighead carp comprise a large portion of this winterkill.
GFP continues to have staff on site to monitor the situation.
GFP fisheries staff monitor winterkill through the spring. Based on the severity and species lost, GFP will make stocking recommendations for impacted waterbodies as deemed necessary.

An added issue is the garbage being discarded from gloves, coats fishing gear and more. On Thursday an effort had been made to clear up that debris.
