Yes, that is another reason for my procrastination, disturbing the eco system. Water scarcity will be felt in the summer months. But the entire city is being connected with pipes with another river - a tributary of River Cauvery from the other side of the city. The politicians are behind this... they want to take the best sweet water to their capital which is 90 miles away [Bengaluru]. River Kabini water is also good, but it is slightly salty [may be to the tongues tasted Cauvery]. We are already getting the water in this. They will disconnect the old Cauvery water line to Mysuru any day. As of now water has been flowing with good force. But you never know when the water flow in the rivers recede in summers. I'm really amazed at your memory - you remember the dam etc!! We have the Kabini dam on this side. Inter-state fight for water continues.... it is a big issue for politicians to raise and the press will be waiting for stories!! They blame our state for storing water in the dam and not releasing and when it is released, there are reports that most of it is let out to the sea!! Dam level is ok as of now and we are in January. So this summer should be just ok.
As for my pond, I have started to top up once a week or so because evaporation also will reduce the levels aside from slow seepage. Drier months are ahead.
