Lakes are often a source of recreation such as fishing, boating and swimming and interior Alaska is no different. Lakes in interior Alaska have also have been used by ancient peoples for thousands of years but now these lakes are currently experiencing changes in water level and water quality. Dr. Mat Wooller and colleagues are working to better understand how lakes respond to environmental changes by piecing together how previous lake levels and water quality were related. They are using lake sediment cores to look back over the past 10,000 years of water levels, local ecology and water quality were related to give us a vision of how interior Alaskan lakes will change in the future.
