Billions of dollars have been spent on the control of nutrient loading to Lake Erie in the U.S. and Canada with the elimination of deep water hypoxia (low oxygen levels) in the central basin of the lake an important goal. In spite of improvements in chlorophyll and phosphorus levels in offshore lake waters, hypoxia appears to have worsened in recent years. There are several hypotheses for the cause of this, including changing climatic conditions, changes in nutrient input from rivers, and the effects of non-native mussels which invaded Lake Erie in the 1980s.

在美国和加拿大，为了控制伊利湖的营养负荷，已经花费了数十亿美元，消除伊利湖中央盆地的深水缺氧（低氧水平）是一个重要目标。尽管近海湖水的叶绿素和磷水平有所改善，但近年来缺氧情况似乎有所恶化。造成这一现象的原因有几种假设，包括气候条件的变化、河流养分输入的变化，以及20世纪80年代入侵伊利湖的非本地贻贝的影响。
