Not mentioned in the BBC story is the impact on water levels of Tis Abay II hydro facility, operating since 2003 on the headwaters of the Blue Nile at the outlet of #LakeTana. I took this photo in Nov. 2003 & met the IMAX film crew in this story: https://t.co/QL5SCFYOlS 2/2
I visited this lake in 2003 while working with LakeNet @WorldLakes and am shocked to see photos of how much the invasive water hyacinth has advanced. BBC News - Ethiopia's Lake Tana threatened by alien weed invasion https://t.co/BAWsDEr1a1 #disappearinglakes 1/2
Thx @mindym1101 for pointing out the misleading title of this otherwise good article about #LakeBaikal (algae mentioned is not toxic). https://t.co/3OZ0OOJ0VE
