Gene Wash Reservoir is a man-made lake located in western Arizona, United States, near Lake Havasu City.

Visual Characteristics

The reservoir is characterized by its expansive, often calm water surface reflecting the surrounding desert landscape. The shoreline consists primarily of desert scrub, rock, and sand. Water color varies with depth and sediment content, typically appearing brown to greenish-brown. The reservoir's perimeter is irregular, with numerous coves and inlets.

Location & Access Logistics

Gene Wash Reservoir is situated approximately 15 miles northwest of Lake Havasu City, Arizona. Access is via State Route 95 North, turning west onto Parker Dam Road (County Road 143). The reservoir is accessible from multiple points along Parker Dam Road, with several unimproved dirt roads leading to shoreline areas. Parking is generally available along the roadside or in designated primitive camping areas. No public transport services operate directly to the reservoir.

Historical & Ecological Origin

Gene Wash Reservoir was created as part of the Colorado River Storage Project. It serves as a forebay for the Parker Power Plant and a regulating reservoir for water releases downstream. The reservoir was formed by the construction of the Gene Wash Dam, completed in 1941. The surrounding environment is arid desert, part of the Mojave Desert ecosystem.

Key Highlights & Activities

Boating, including powerboating and personal watercraft, is a primary activity. Fishing for species such as largemouth bass, striped bass, and catfish is permitted. Kayaking and paddleboarding are also possible. Primitive camping is allowed in designated areas along the shoreline.

Infrastructure & Amenities

Basic amenities are limited. There are no developed facilities such as restrooms, picnic tables, or shade structures directly at the reservoir. Cell phone signal is intermittent to non-existent in most areas. Food vendors are not present at the reservoir; visitors should bring all necessary supplies from Lake Havasu City or Parker.

Best Time to Visit

The best time for water activities is during the spring (March-May) and fall (September-November) when temperatures are moderate. Summer months (June-August) experience extreme heat, making daytime activities challenging. Early morning and late afternoon offer the most comfortable conditions for outdoor recreation. There are no tide considerations as it is a freshwater reservoir.

Facts & Legends

Gene Wash Reservoir is named after Gene Wash, a former Bureau of Reclamation engineer. A specific tip for visitors is to be aware of potential flash flood risks during monsoon season (July-September), as low-lying areas near washes can become inundated rapidly.
