Fertilizer runoff
Explanation:
Fertilizer runoff is the most likely cause of increased algae growth in local ponds after heavy rainfall. Nitrogen and phosphorus fertilizers wash into bodies of water during rains, leading to excessive algal growth, which can lead to eutrophication and oxygen depletion.
