Water Systems & Aquatic Life

Service Description

Located in Lakeside, CA, Lake Jennings is a scenic reservoir tucked into the rolling foothills of East San Diego County. This man-made lake plays a vital role in the region’s water system, supporting both human needs and local ecosystems. On this hike, students will walk a gentle loop trail along the lake’s edge and explore how rainfall, erosion, and reservoirs are interconnected. Along the way, students will examine how rain runoff travels from surrounding hills into the reservoir, shaping the shoreline and bringing nutrients into the lake. They'll also observe erosion in real-time—spotting places where water has carved channels in the landscape and changed the terrain. One unique aspect of Lake Jennings is its diverse fish population, which includes species such as trout, catfish, bass, and bluegill. The lake is regularly stocked to support fishing and help balance the aquatic ecosystem. This hike will introduce students to the basics of fish stocking practices, the importance of healthy water systems for fish survival, and how erosion can both help and harm aquatic habitats. Educational Highlights: 💧 Where Does Rain Go? – Follow the journey of rain as it collects in the watershed and enters the reservoir. 🌊 Erosion in Action – Observe areas where water has shifted soil and changed the shape of the land. 🐟 Fish & Freshwater Habitats – Learn about the fish species in Lake Jennings and how stocking works to support the ecosystem. 🌱 Protecting the Shoreline – Understand how native plants and human efforts reduce erosion and keep the water clean. This hike is ideal for students curious about water science, aquatic biology, and conservation. With plenty of spots to pause, observe, and learn, Lake Jennings offers a memorable hands-on experience connecting land, water, and life.
