Lake Levels
The Lake Level and flume channel depth/flow were consistent with the guidelines for lake management during 2023 as there was ample rain. In contrast, lake levels fell during summer 2022 due to the drought.
Year to date Rainfall and Temperature underscore the impact of drought and heat on water quality and lake level. Here are historical weather and historical lake level data, which varies with the pattern of rain. Also, in 2014 and 2018 treatment of the invasive weeds with herbicides required lowering of the lake level to protect an endangered plant that can be found along the shore of the lake.
Managing the rate of water flow out of the lake into Massapoag Brook helps keep the lake clean and cooler, and is an important job of the Conservation Administrator. Here are the Procedures and Schedules for Controlling the Water Level in Lake Massapoag.
