All dams have a spill way where the "excess" water overflows. Just like your sink has a small hole hapo juu that drains the excess water when your sink is full so as not to flood your house. A dam overflow is actually a good thing. If the patel dam had a spillway that allowed the water to overflow, it wouldn't have collapsed.

A spillway as i said is just like that small hole kwa your sink. When you get to the spill (overflow) level all it means is that the water coming from the tap into the sink will be drained without settling in your sink. Same with masinga. It means the waters flowing into the dam will not be stored but will flow just like the river used to flow uninterrupted. However huko downstream there are other dams that will store this "overflowed" water. Also note that flooding in the tana isnt caused only by water from "upcountry". It is raining in the whole country including areas downstream beyond the dams huko garissa, hola, garsen, tana river delta itself etc and all that water ends up in the river. Masinga dam and spillway to the right. When the dam gets full the excess water flows downstream without going through the hydropower turbines (of course not the same water molecules if you get what I mean).

That is like saying that no NASA principal is more superior than the other. Weta and mdv "learnt" the hard way.

Spilling began at 4 "There are only two emotions in the market, hope & fear. The problem is you hope when you should fear & fear when you should hope: - Jesse Livermore

The spillage is more of a trickle...  I don't see it causing any harm downstream.
