在威斯康辛的银湖中, 冬季的鱼群死亡, 很可能是由于冰封氧气, 促使DNR调查及春季的恢复调查。 A winter fish kill in Wisconsin’s Silver Lake, likely due to ice blocking oxygen, prompts DNR investigation and a spring recovery survey.

威斯康星州Manitowoc县Silver Lake的一条鱼被杀死,导致DRR调查低氧水平,特别是在西南角,在那里,水下摄像头发现每个地点有5至10个死鱼。 A fish kill in Silver Lake, Manitowoc County, Wisconsin, has led the DNR to investigate low oxygen levels, particularly in the southwest corner, where underwater cameras found 5–10 dead panfish per site. 未发现任何污染或径流,而且该事件可能与冬季鱼类的捕杀模式有关,这种模式来自冰盖,限制了氧的交换。 No pollution or runoff was detected, and the event is likely linked to winter fish kill patterns from ice cover limiting oxygen exchange. 国家档案局排除了污染,并计划在冰融化后进行一次春季调查,以评估恢复情况,预计人口将在7年内全面恢复。 The DNR ruled out contamination and plans a spring survey after ice melts to assess recovery, with full population restoration expected in up to seven years.
