Lake Tahoe inflow streams contribute 310,000 acre-feet (0.38 km 3) of the 530,000 acre-feet (0.65 km 3) of water that flows through Lake Tahoe every year. [2] The list, below, groups rivers and creeks that flow into the lake by their locations on the north, east, south and west shores, in a clockwise order.
Honey bees are incredibly social insects. They live together in big groups with other bees in an organized society that scientists call eusocial, which means every bee has a job to do. This could ...

The park is in the high Sierra Nevada mountain range at an elevation of around 1,900 metres (6,200 ft). It is covered in mixed coniferous forest with tree species such as Jeffrey pine (Pinus jeffreyi), white fir (Abies concolor), Sierra lodgepole pine (Pinus contorta ssp. murrayana), California incense cedar (Calocedrus decurrens), sugar pine (Pinus lambertiana), and red fir (Abies magnifica).
