Algae are not influenced much by day length like many land plants are. Optimal conditions for algae blooms are high nutrient levels, calm water, clear water allowing sunlight penetration, and warm air/water temperatures. It's actually the live algae causing the algae colonies to float to the surface. When the blooms first appear they are quite green, later in the season they can look quite brown because there are many dead cells in the colony. Each algae cell has a limited life span like most organisms, and it's relatively short. If there were no live cells in the colony, the dead cells would soon sink to the bottom where bacteria would consume them and consume oxygen in the process.
Strawberry is definitely a dimictic lake (2 mixes per year).
