I long for clear ice on top like that pictured above. My ice usually has some frozen slush on top making the top layer the color of milk jug. Clear ice is almost like window glass and it lets lots of sunlight for photosynthesis of phytoplankton into the water below when ice is clear of snow. I analyzed some reservoir water today that had 6 ft of clarity just before hard freeze up. Currently the phytoplankton density was 986,000cells/ounce of water. If they can get light they will make dissolved oxygen.
