加州圣贝纳迪诺县 Chino Hills 公园蓄水池约 200 条鱼死亡：初检为溶解氧偏低
位于加州圣贝纳迪诺县的 Chino Hills 市政府 10 月 21 日发布水质检测更新：10 月 9 日，市府工作人员在 English Springs Park 的蓄水池中发现约 200 条死鱼，随后清理鱼尸并采集水样送检。
市府表示，截至 10 月 21 日的初步结果显示，唯一明显异常是溶解氧偏低；溶解氧低并不直接导致鱼类死亡，但会造成显著压力，且采样前氧含量可能曾进一步下降。市府说明，该水体是用于收集与管理雨水径流的蓄水池，并非休闲湖泊，市府从不在其中投放鱼、龟或其他水生生物，也不以维持鱼群为目标管理，池中水生生物相信是访客私自放入的。市府呼吁公众不要向池中放生鱼、龟或其他水生动物。
About 200 Dead Fish Found in Chino Hills Park Basin; Preliminary Tests Point to Low Dissolved Oxygen
The City of Chino Hills, in San Bernardino County, California, issued a water quality update on October 21: on October 9, city staff discovered approximately 200 dead fish in the detention basin at English Springs Park, removed the fish and collected water samples.
As of October 21, preliminary results showed only one notable anomaly — a low dissolved oxygen level. The city said low dissolved oxygen does not directly cause fish mortality but can cause significant stress, and that oxygen levels may have dropped further before samples were collected. The city noted that the water feature is a detention basin designed to collect and manage stormwater runoff, not a recreational lake; the city does not stock the basin with fish, turtles or other aquatic life and does not manage it to maintain a fish population, and the aquatic life present is believed to have been introduced by visitors. The city asked the public not to release fish, turtles or other aquatic life into the basin.
