Lake Ice

How quality is the GPR data coming from on frozen lake and the boat on the water surface? The goal is to measure the ice thickness and sediments beneath the lake. Please tell me the details, thanks

I am planning to fish Wollaston Lake and/or Reindeer Lake in Saskatchewan in mid-June. The long winter and cools spring suggests that there may still be ice on those lakes late into June. Is there any way to forecast when ice may be out?
Thanks,
Bert
