Ultimately the sole cause of different species is restricted breeding. Males and females of one species will only mate with males and females of the same species.
Now there may be a secondary factor that is the main cause, such as geographic isolation. The two species develop separately because there is a mountain range in between them and the males of each type can't get access to the females of the other type. But as you can see it is the restricted breeding that ultimately does it.
Now for two species of stickleback in the same lake. It may be that the females are finicky in their chose of mates and prefer male with a certain colour pattern, or they prefer nests built at a certain depth which males have an inclination to build at different heights.

How did humans change mono lake?
Humans have altered Mono Lake primarily by diverting water from its tributary streams, leading to a decrease in the lake's water levels. This diversion has disrupted the lake's ecosystem, causing a decline in the population of the native species. Additionally, pollution from agricultural runoff and urban development has further impacted the lake's water quality.

What are the effects of human activity on lake development?
Human activity significantly impacts lake development through pollution, habitat alteration, and water management practices. Urbanization and agriculture can lead to nutrient runoff, causing eutrophication, which depletes oxygen levels and harms aquatic life. Deforestation and land development can disrupt natural drainage patterns and sediment flow, affecting lake morphology and biodiversity. Additionally, dam construction alters water levels and flow, impacting ecosystems and the species that depend on them.
