The warm days are definitely settling into the upper water column now - you have to get below 20' to get water under 70 degrees. Keep that in mind when looking for fish....
Memorial Day has past which means "Summer" is here - though our water temps are still a little cooler than normal on the surface - however, with days in the 80s or more, it won't be long before we see a lot warmer temps. Please keep in mind that as temperatures rise, Catch & Release of striper becomes harder - especially when fishing with umbrella rigs or other techniques that result in longer fights with the fish in the upper levels of the water column.
Our "Man on the Water", Joel J, diligently collects water temperature measurements across the lake.
