Lake Hennessey, a serene reservoir cradled in the Vaca Mountains east of St. Helena, offers a refreshing counterpoint to the celebrated vineyards of Napa Valley. Formed in 1948 by the construction of the Conn Creek Dam, this 31,000-acre-foot reservoir serves as a primary water source for the City of Napa, while also providing a tranquil recreational area for locals and visitors alike. Named after Edwin R. Hennessey, a local civic leader instrumental in the reservoir's development, the lake presents a picturesque landscape of rolling foothills, verdant vineyards, and fragrant pine forests. While Lake Hennessey's primary function is to supply water, it welcomes the public to engage in various outdoor activities. Fishing is a popular pursuit, with the lake teeming with diverse species such as largemouth bass, rainbow trout, channel catfish, crappie, bluegill, and sunfish. Anglers can cast their lines from the shore or venture onto the water in boats, subject to certain restrictions. A valid fishing permit is required for those 16 years or older, contributing to the lake's upkeep and conservation efforts. Remember to adhere to California Department of Fish and Wildlife regulations regarding fishing rules and limits. Boating is permitted on Lake Hennessey, offering a peaceful way to explore the reservoir's approximately 9 to 10 miles of shoreline. However, to maintain the tranquility and protect the water quality, a 10 mph speed limit is enforced, restricting the use of larger, high-powered motorboats. Kayaks and canoes are ideal for navigating the calm waters, allowing paddlers to fully appreciate the surrounding scenery and observe the diverse wildlife that inhabits the area. Please note that due to its function as a water source, swimming, wading, and any bodily contact with the water are strictly prohibited. Beyond the water, Lake Hennessey boasts a network of hiking trails that wind through the surrounding hills and forests. These trails offer stunning views of the lake, the Napa Valley, and the distant Mayacamas Mountains. The Lake Hennessey Shoreline Trail provides a relatively easy stroll along the water's edge, while the Alta Hennessey Trail climbs into the hills, rewarding hikers with panoramic vistas. For a more challenging trek, explore the Sam the Eagle Trail, which traverses a low ridge with filtered views of the lake. Keep an eye out for the diverse birdlife that calls Lake Hennessey home, including bald eagles, osprey, woodpeckers, and various species of waterfowl. The area around Lake Hennessey is also rich in history and natural beauty. Nearby Moore Creek Park offers additional hiking trails and opportunities for outdoor recreation. The park's Lake Hennessey Unit provides access to the lake's southern shoreline and connects to the various trails that wind through the surrounding hills. The Napa Valley Vine Trail, a paved bike path, extends to St. Helena, offering a scenic route for cyclists to explore the region. For those interested in the area's history, a visit to the Bale Grist Mill State Historic Park provides a glimpse into Napa Valley's agricultural past. While visiting Lake Hennessey, it's important to be mindful of the environment and adhere to the park's regulations. Pack out all trash, stay on designated trails, and respect the wildlife. Remember that Lake Hennessey is a vital water source, so it's crucial to avoid any activities that could pollute the water. With its stunning scenery, diverse recreational opportunities, and commitment to conservation, Lake Hennessey offers a refreshing escape from the ordinary and a chance to connect with nature in the heart of Napa Valley. Recent concerns about the invasive golden mussel have led to temporary closures and restrictions on boating activities. Before planning a visit, check the Napa County Regional Park District website for the latest updates and regulations.
