Deep within the Laguna Mountains, a vital stream begins its journey: Cottonwood Creek. This creek is more than just a waterway. It’s a thread woven into San Diego County’s history.
Cottonwood Creek stretches 36 miles. It plays a crucial role in the Tijuana River drainage basin. Its source lies high in the Cleveland National Forest, near Pine Valley. Imagine the water’s pure descent from 5,406 feet.
The creek flows south. It carves its way through the picturesque Cottonwood Valley. The creek feeds into Lake Morena, held back by the Morena Dam. Below the dam, Cottonwood Creek takes a sharp turn west. It surges through a narrow gorge toward Barrett Lake, the result of the Barrett Dam.
From Barrett Lake, the creek veers south. It flows past Barrett Junction. Then, it merges with Tecate Creek. Together, they form the Rio Alamar. This confluence is a stone’s throw from the US-Mexico border, about 200 yards north. Interestingly, both Tecate Creek and the Rio Alamar are mainly in Mexico.
Did you know Cottonwood Creek contributes to San Diego’s water supply? Morena and Barrett Reservoirs are part of the city’s municipal system. Water from the creek travels through the Dulzura Conduit to Lower Otay Reservoir. However, Cottonwood Creek provides only a fraction of San Diego’s water. The city mainly relies on imported Colorado River water.
For those seeking natural beauty, Cottonwood Creek Falls offers a rewarding experience. While less famous than Cedar Creek Falls, it boasts a series of cascades and small pools. It is often less crowded. The trail to the falls is unofficial adding to the sense of adventure.
The hike involves navigating overgrown paths. One must squeeze past prickly pear cactus. The sound of rushing water guides hikers closer to the falls. The reward is a series of cascades. Exploring the canyon requires some rock scrambling skills.
Cottonwood Creek. It’s a testament to nature’s enduring power. It’s a vital part of San Diego’s ecosystem. It offers both sustenance and scenic beauty. As the water flows toward the Rio Alamar, it carries stories. It connects landscapes and communities across borders.
