Dear Mark,

After earlier delays due to  weather conditions and more recently with COVID-19, Phase 2 of the  

Silver Lake Dredging Project has been completed. The following are the results of the sediment 

sampling and bathymetric survey that was completed during this phase :

Sediment Sampling Overview:

Included with this correspondence is a map indicating the sediment sampling collection points. One 

sample near the  Walker Road bridge had a DDT (and its derivatives) level slightly above the  Class A threshold level, and one sample closer to the main lake body with copper slightly above Class A level. Overall, and as expected, the sediment in the main lake had lower levels of contaminants than the Outlet sediments and with only minor exceedances and could be argued to be Class A 

sediments only.

Survey Results

Attached is a map ( See below) indicated the results of the bathymetric survey assessment, depth of sediment and locations are identified. Based on this information there is approximately 36,000 cubic yards of sediment in this portion of Silver Lake. This estimate also includes areas partially within the NYSDEC WMA and all along the edges of the  shoreline but  does not  include the material identified in the outlet study. The amount of 

sediment identified in the outlet study will be included as part of the total dredging project . 

With this supporting data, a preliminary plan of action is being developed to submit, and discuss with, NYS DEC. Once this has occurred, and we are provided with feedback, another meeting of the Silver Lake Dredging Committee will be held to review the options available to complete future phases of this much needed dredging project. While funding options are limited now, primarily due to the COVID-19 crisis, it  is the  goal of this agency to  be prepared to move forward on this project once those opportunities are made available  .

With the Silver Lake Association being a primary member of the Silver Lake Dredging Committee, and 

as part of the memorandum of Understanding addressing Phase 2 funding (Copy Attached), an invoice in the amount of $14,975.00 also included with the correspondence for your attention .

I look forward to meeting with you in the near future as we review the options presented to complete the dredging project but  if  you should have any questions please do not hesitate to contact me.

Sincerely,

Stephen D. Perkins

The yellow icons on the map indicate where samples are proposed to be taken.  Sampling will be conducted in both the area to be dredged and where the sediment is to be deposited.
