Lake Shasta: A Brief Overview

Lake Shasta is the largest reservoir in California. It is a popular recreational area located in the Northern part of the state. Shasta Dam, which impounds the waters of the Sacramento River, created the massive lake. The lake covers approximately 30,000 acres (12,000 hectares). It has a maximum depth of 517 feet (157 meters) when it’s at full capacity. Lake Shasta is fed by the Sacramento River and its tributaries. It serves as a critical reservoir in California’s water management system, storing water for irrigation, municipal use, and hydroelectric power generation. Commencing in 1938, construction of the dam was completed in 1945. As a result of the dam construction and the subsequent filling of the reservoir, several towns and communities were either partially or entirely submerged.

Kennett, California

Creating reservoirs has historically required displacing or submerging entire towns. Reservoirs are typically formed by damming rivers, which results in the flooding of the surrounding valleys. Kennett, California was the principal town affected by the creation of Lake Shasta. Kennett was established in the late 1800s as a railroad stop on the C&O Railroad line. In the early 20th century, the Mammoth Copper Company brought a copper smelter to the town. The smelter refined the copper being mined in the area.

Kennett was a classic company town. The mining company not only operated the mines but also provided housing and amenities for its employees and their families. The town’s infrastructure and facilities were largely owned and controlled by the mining company. In his heyday, Kennett boasted a bustling commercial area, a school, a hospital, and a hotel. Legend has it that while many of Kennett’s residents sold their land to the government and moved on, a few stubborn holdouts didn’t leave until the water started to rise! Now the town lies hundreds of feet (meters) beneath the surface of Lake Shasta.

Water sports like water skiing, wakeboarding, and jet skiing are also popular. Houseboat rentals are a splendid way to explore the lake.

Lake Shasta Caverns

No trip to Lake Shasta is complete without a trip to the caverns. The Lake Shasta Caverns are on the McCloud arm of Lake Shasta. To reach the caverns, visitors take a boat ride across Lake Shasta, providing scenic views of the lake and the surrounding landscape. The boat ride is followed by a short shuttle bus ride to the actual cavern entrance. Once they have arrived, visitors are greeted by the splendor of the majestic limestone caves. The caverns allow visitors to explore the fascinating underground world of stalactites and stalagmites. Until the mid-20th century, only the most intrepid spelunkers were able to access the caverns. Since then, a friendlier approach to the caverns was created. Nowadays the caverns attract thousands of visitors annually.
