Adirondack Lake Assessment Program (ALAP)
ALAP is a joint project between Protect the Adirondacks and the Paul Smith’s College Adirondack Watership Institute.
Each PDF contains data for numerous lakes across the Adirondacks. The charts shown below are specific to Chase’s Lake for the years that our lake was included. The link to the full report for each year is provided for completeness.

Citizens Statewide Lake Assessment Program (“CSLAP”)
CSLAP Data:
CSLAP is directed by the NYS DEC in collaboration with the NYS Federation of Lake Associations (“NYSFOLA”).
CSLAP sampling was done in 1990, 1991, 1992, 1993, 1995, 2022, 2023 and 2024.
1990, 1991, 1992, 1993 are at this link called the “CSLAP Report Search”. However, for these years (1990 through 1993), you have to search by year and leave the Lake name blank, and leave the County and Report type to the default setting of “All”:

We have provided links to the individual reports for those years below, however the data is not always presented in a consistent format. We have also provided screenshots of the long term trends on the following pages, but note that there are significant gaps in the reporting between 1995 and 2022.
