BHS Pond Monitoring
Barnstable High School Pond Monitoring
Over the 2019-2020 academic year BCWC hosted 2 student interns from Barnstable High School. Sofia Hailu and Graham Hempstead joined us through BHS’s Senior Internship Program. They conducted weekly sampling at Long Pond, Bearse Pond, and Wequaquet Lake, and began building a database from their results. Given the cyanobacteria blooms in a number of ponds in summer 2019, having year-round water quality data from these ponds is more important than ever.
Due to COVID-19 restrictions, a BCWC staff member has been conducting the weekly sampling at Long Pond, Bearse Pond, and Wequaquet Lake instead of interns from Barnstable High School.
BHS Environmental Club
In the fall of 2017, BCWC began working with members of the Barnstable High School Environmental Club on a winter pond monitoring project. The purpose of the project was to expose high school students to hands-on field work using water sampling equipment. Three monitoring locations were chosen in Centerville that are close to the high school: Lake Wequaquet, Bearse Pond and Long Pond. Each of the sampling sites has a dock that is accessed through a private homeowner’s property.
At each monitoring site, the students record visual observations and physical conditions, look for macroinvertebrates, and collect water samples to test for nitrate/phosphate levels and the presence of cyanobacteria.
For visual observations and physical conditions, the students note water, weather, and wind conditions, take air and water temperatures with thermometers, use dissolved oxygen meters to measure the dissolved oxygen levels in the water, measure depth and turbidity using a Secchi disc, and record waterfowl sightings and vegetation growth in the sampling area.
Using dip nets and shovels, students gather bottom debris and sediment and sort through it looking for macroinvertebrates. A dichotomous key is used to help identify any organisms found. Commonly seen macroinvertebrates at these three freshwater sites include damselfly and dragonfly nymphs, crayfish and diving beetles.
Water samples are collected at each site. The students test for nitrate and phosphate using Hach test kits.
