The Cortland - Onondaga Federation of Kettle Lake Associations, Inc. (COFOKLA) is dedicated to the preservation of the kettle lakes, surrounding waters and watershed regions in Cortland and Onondaga counties. COFOKLA does so by advocating awareness of lake resources, educating communities about watersheds and their protection, and promoting stewardship of those waterways.

COFOKLA was formed as vehicle to share access to information, provide watershed planning with a unified approach, and bring outreach and education to a broad audience. All our watersheds are connected either by tributaries or groundwater. Current members include associations from Song Lake, Crooked Lake, Tully Lake, and Little York Lake.

What is a Kettle Lake? Preble is a unique and beautiful region. One of its defining characteristics is the presence of several kettle-hole or kettle lakes. According to the United States Geological Survey (USGS), the area was formed by the advancing and retreating of glacial ice during the last glacial period in North America. To the west of us, the same glacial process formed the Finger Lakes. The process here caused smaller holes to be formed when huge chunks of ice broke off the glacier. These holes, or “kettles” were then buried by till1 as the glacier receded. When these ice chunks melted, the depression remained.

Each kettle lake has its own unique properties. Some have natural or created outlets, while others are landlocked. All of these lakes are, however, connected to the surficial aquifer. A surficial aquifer is generally defined by the USGS, as an “unconfined, shallow aquifer system, recharged by rainfall and leakage from surface water bodies.”

The glaciers also formed the Valley Heads Moraine, an area of sand and gravel deposited when the retreating ice paused. The moraine runs east to west and separates the Tully Valley to the north from the Tioughnioga Valley to the south. This moraine also forms the surface water divide for the St. Lawrence River drainage (north) and the Susquehanna River drainage (south).

As part of their outreach and education program, each C-OFOKLA meeting begins with a short presentation from an expert or professional on a variety of water quality issues. If you are interested in learning more please call Tarki Heath at 696-5262. All presentations are open to the public.
