The north end is warmer most of the time in the northern hemisphere because of sun exposure. The sun is over the equator, so therefor it is to our south. Therefore any banks or slopes that face the south will get more direct sunlight then those banks facing the north. the banks on the north end of the lake, face south, and therefor warm up better. Im not sure if water flowing in has much to do with it.

Next time your at santa margarita, look at the hills around there. You will find that the vegitation on the south facing slopes is completely different than those slopes facing north. The north facing slopes will appear slightly more lush than the dry sunbeat south facing sides. This is becase of the same phenomina called "aspect" in ecological terms.

Hope that helped
