Watershed Explorers

San Dieguito Lagoon


Led by the San Dieguito River Park, students engage in several activity stations  to learn about the importance and diversity of the lagoon. Activities include an  interactive Ranger-led hike along the Lagoon Trail, testing water samples at the  stormwater treatment ponds, studying skulls of animals found within the park,  viewing native plants and learning about their adaptations and use, and  creating nature-inspired artwork using materials collected from the lagoon.


Students will:

  • learn about habitat destruction, degradation, restoration and preservation;
  • learn about urban runoff, freshwater and salt water, and the importance of water quality;
  • learn about habitat types and how plants and animals have adapted to living at the San Dieguito Lagoon;
  • understand their role in keeping the watershed healthy.
