IMPORTANT UPDATE: As of 2023, Pecks Lake no longer contains water, as the diversion from the Verde River that previously fed the lake has ceased. Historical paddling information is retained below for reference only.

Pecks Lake was a small reservoir near Clarkdale, Arizona, created in an ancient oxbow that was cut off from the Verde River approximately 10,000 years ago. Located within the Tuzigoot National Monument area, the lake was historically fed by a diversion tunnel from the Verde River on its northwest corner.

The lake and surrounding Tavasci Marsh supported over 100 species of migrating birds, making it a significant wildlife viewing destination designated as part of the Tuzigoot Important Bird Area. Winter months brought numerous waterfowl species including canvasback, common mergansers, redhead and ring-necked ducks, wigeons, gadwalls, and teals. Great blue herons, river otters, and beavers were also common residents.

The property, owned by Freeport-McMoRan, was originally developed as part of a planned golf course. The lake's history is tied to the region's copper mining operations, as it provided process water for a nearby smelter. The surrounding area includes capped and re-vegetated tailings from the former Clarkdale copper smelter.

Prior to its draining, the lake faced challenges with eutrophication and was becoming choked with aquatic plants, including invasive water lilies and Eurasian milfoil. The fish population included non-native species such as northern pike, yellow perch, smallmouth bass, and sunfish.

Until 2003, the Town of Clarkdale maintained a lease that allowed public access for fishing and recreation. After the lease expired, public access was restricted. The water temperature remained relatively stable at 68°F year-round due to the spring-fed nature of the connected Tavasci Marsh.
