This lake has 8 Layers or 15 Layers for HD Version

Wallum Lake is a pristine 322-acre natural lake situated on the border between Burrillville, Providence County, Rhode Island and Douglas, Worcester County, Massachusetts. With an average depth of 28 feet and reaching a maximum depth of 81 feet, this spring-fed waterbody is renowned as the freshest, cleanest, and coldest lake in Rhode Island, featuring crystal-clear water with visibility typically extending to 20 feet. The lake's bottom is composed primarily of rock and boulders with minimal aquatic vegetation, creating excellent habitat for diverse fish populations. Fed by underground springs, Wallum Lake maintains exceptional water quality and a cold oxygenated layer throughout summer months that enables trout to thrive year-round. The western and northern shores lie within the 5,700-acre Douglas State Forest in Massachusetts, while the southern portions border the nearly 2,000-acre Buck Hill Management Area in Rhode Island, ensuring that large sections of the shoreline remain protected and undeveloped. The lake stretches almost two miles in length and ranges from one-quarter to one-half mile in width, providing ample space for various water-based activities while maintaining its natural character.

Wallum Lake has earned recognition as one of southern New England's premier fishing destinations, regularly stocked with rainbow trout and brown trout by both Massachusetts and Rhode Island wildlife agencies. The lake supports healthy populations of landlocked salmon, including occasional broodstock salmon that can exceed five pounds, alongside largemouth bass, smallmouth bass, chain pickerel, yellow perch, pumpkinseed, bluegill, yellow bullhead, brown bullhead, landlocked alewife, and rainbow smelt. Smallmouth bass thrive along the rocky, boulder-strewn shores throughout the lake, while largemouth bass congregate in the small coves and shallower waters of the southern basin. Two paved boat ramps provide convenient access: one at the northern end off Wallum Lake Road in Douglas, Massachusetts, complete with parking for 30 trailers, and another at the southern end in Burrillville, Rhode Island. The lake welcomes both motorized and non-motorized boats, though hand-carry boat launches are also available for canoes and kayaks. Beyond fishing and boating, Douglas State Forest offers extensive recreational facilities including a popular swimming beach, pavilions, picnic areas, miles of hiking trails including a section of the Midstate Trail, and a rare Atlantic White Cedar swamp accessible via boardwalk. With fishing licenses from either state accepted and the lake's unique position straddling two states, Wallum Lake provides year-round recreational opportunities for anglers, paddlers, and nature enthusiasts seeking a pristine wilderness experience in a protected natural setting.

The difference between standard and HD maps is the number of layers. Standard maps have 1 land layer and 7 water layers. " The HD lake maps have 1 land layer and 14 water layers. So twice the detail. The HD Maps are limited to Extra Large, " XX Large, and Gigantic sizes only. On the smaller sizes the depth change of the wood is too extreme and you end up losing detail."
