Lake Quinsigamond (also Long Pond) is a body of water situated between the city of Worcester and the town of Shrewsbury in Worcester County, Massachusetts, United States. It is 4 miles (6 km) long, between 50 and 85 feet (15 and 26 m) deep, and has a surface area of approximately 772 acres (3.1 km²). Lake Quinsigamond hosts 8 islands with the majority owned by private citizens. Two islands are connected to land via bridge. The largest island, Drake Island, is still state owned. Water from the lake empties into the Quinsigamond River in the Blackstone Valley. Bridging the lake The lake's long and narrow shape posed a challenge to settlers of the Worcester area in the 17th century since it was deeded by Peter Jethro and other Native Americans in 1665. Lacking modern bridging techniques, westward travelers had to ride around the lake's northern and southern tips. At the turn of the 19th century, Isaiah Thomas, a Worcester resident, developed plans for a direct link between Worcester and Boston (plans that eventually became Route 9). Construction of this road was under the authority of the Worcester Turnpike Corporation (until 1841; thereafter, the city of Worcester). Like the settlers 150 years earlier, Thomas and company faced the problem of Lake Quinsigamond. The first span across the lake was a floating log bridge, built in 1806. This first attempt was unstable, often swaying under the weight of horse-drawn wagons. The floating bridge was broken apart by waves in 1806, and was rebuilt in the year 1807 as an interim solution. The second bridge was an early suspension bridge, and was completed in early 1817. Nine wooden piers, built into the lakebed at regular intervals, held aloft a gravel-covered plank bridge. Due to the unstable nature of the lakebed, the nine piers settled at different levels, causing gaps to appear in the road surface. The piers and the bridge split apart and fell into the water on September 19, 1817. The collapse of the suspension bridge was quickly followed with a second floating bridge, this one lasting until 1861. The first stable bridge over Lake Quinsigamond (the fourth such attempt overall) was an earthen causeway, finished in 1863. Formed from a mixture of rock, gravel and dirt, the causeway was the first span to not sway under heavy loads. The causeway effectively split the lake in half, stifling the nascent lakeside steamboat
