Year 10 Science Excursion to Brent Reservoir

The excursion began with an informative talk delivered by Ms Nowuje Ali, who explained the history and purpose of the reservoir and dam. Students learned that Brent Reservoir, also known as the Welsh Harp, was created in 1835 by damming the River Brent. The reservoir was originally constructed to provide water for the Grand Union Canal system during the Industrial Revolution, supporting transport and trade across London. Over time, the area developed into an important site for wildlife conservation and recreation.

Following the introduction, students walked along the dam, observing the structure and surrounding landscape. The group then continued to the sluice and gates, where the reservoir feeds water into London’s canal network. During this section of the trip, discussions focused on water management, flood control, and the importance of maintaining canal water levels.

Students were also introduced to the role of green vegetation surrounding the reservoir. The environmental importance of the vegetation was discussed, including how plants help prevent soil erosion, improve water quality, provide habitats for wildlife, and contribute to biodiversity within the ecosystem.

As part of their fieldwork activities, students undertook several independent exercises. These included observational tasks and producing a detailed sketch of the spillway. The exercises encouraged students to apply geographical skills such as field sketching, observation, and environmental analysis.

Overall, the excursion was both educational and engaging. Students gained valuable insight into the historical development, environmental importance, and management of Brent Reservoir while developing practical geographical fieldwork skills outside the classroom.
