The longest of the Finger Lakes and second largest in area, Cayuga Lake is also the closest to sea level. It's waters are regulated by Mud Lock at the northern end, which helps prevent flooding and costal ice damage. Although the majority of the lake is too deep to freeze over in winter, the southern end is much shallower and will often get a coat of ice.

The northern tip is capped by vast marshland, the majority of which is designated as the Montezuma National Wildlife Refuge, an ecologically important wetland for water quality and bird migration. This wetland area serves as both a natural water filter and an important breeding ground for waterfowl.  Despite this important natural area, the Northern end has a long history of public works projects. Locks, railways, highways and canals are all adjacent to this northern tip and contribute greatly to water quality and ascetic concerns.

The Seneca River Canal was developed to connect the northern tips of Seneca and Cayuga Lakes to the NY State Barge Canal system. Despite the obvious mixing of foreign waters, increasing the opportunity for invasive species, this system granted access to the two large, isolated Finger Fakes to the rest of the state.

At the southern end, you'll find the booming city of Ithaca, home to Cornell University and Ithaca College. An upstate 'mecca' for culture, diversity and nature. The convergence of numerous gorges into the Cayuga Inlet within Ithaca, give this city a beautiful atmosphere and an abundance of natural recreation opportunities.

The rolling hills that isolate the Finger Lakes are optimal for agriculture. With temperate climates, nutrient-rich glacial soil and readily available freshwater, the surrounding land has become a hot-bed for refined produce. The conditions present between Seneca and Cayuga in particular are ideal for grape cultivation.  The two  lakes host some of the nation's premiere wineries and the area is benefiting greatly from tourism.

The lake's calm and productive waters have also made it popular for sport and recreation. The coast and surrounding hills are dotted with homes and cottages. Boating and fishing are popular activities, with fishing derbies abundant and small sport-craft a common sight. Yacht clubs and private marinas can also be found along the coast, demonstrating the area's passion for this calm, miniature sea. The many public beaches along the shore offer visitors to swim or fish in the lakes cool waters.

Beyond recreation, the lake is also used as a source of freshwater and cooling. Using lake-source-cooling methods, industries and businesses, such as Cornell University, pump the lake's naturally cool waters to use as a heat sink to cool buildings and machinery.

The combination of plentiful surrounding agriculture, development, industrial and recreational use as well as illegal dumping has put the water quality at risk. Since the Lake's water's do not cycle as fast as the smaller lakes, the natural cleaning process is beginning to have less of an impact. Efforts are currently underway to improve the water quality of Cayuga Lake.
