Lake Ivanhoe, also known as Round Pond, is a tiny 68 acre lake which lies north of Great East Lake within a 455 acre watershed. The small size of the watershed makes Lake Ivanhoe extremely manageable, but also increases the impact of each site on the lake. Unlike most lakes in the region, Lake Ivanhoe has no traditional inlets or outlets, but will drain over land into Great East Lake. Historically there was a river between Lake Ivanhoe and Great East, however this was filled in by construction. Lake Ivanhoe maintains moderately good water quality despite having a low pH. Lake Ivanhoe is considered an oligotrophic lake.
