===The Lake===
Spring fed Peach Lake is located in the towns of [[North Salem, New York|North Salem]] and [[Southeast, New York|Southeast]]. The lake is {{convert|1.5|mi}} long, {{convert|0.5|mi}} wide at its center, and reaches a maximum depth of approximately {{convert|24|ft}}. Its western side is deeper than the eastern, unequally scalloped by glacial gouging. A sharp [[thermocline]] is present at a depth of about {{convert|11|to|13|ft}}<ref>{{Cite web|url=https://www.lakelubbers.com/peach-lake-2407/|title=Peach Lake, New York, USA Vacation Info|website=Lakelubbers|access-date=2019-03-26}}</ref> where the water temperature may change {{convert|15|F}} within an inch. This thermocline protects the lake from excessive weed growth in areas of the lake that are deeper than the thermocline layer, as it is simply too cold for the weeds to start growing. This temperature gradient is caused by the natural springs that feed the lake. There are no rivers entering the lake and only a very small intermittent stream on the southeastern corner.

The lake is a Class B reservoir for the [[New York City water supply system]] and, unusually for the area, outflows north through Peach Lake Brook into the [[East Branch Reservoir]] in the town of [[Southeast, New York|Southeast]], which is part of the [[New Croton Reservoir|Croton Reservoir]] system.
