I used to go in and around KR Puram Lake many times but I never observed the improvements happend in the lake.
Now, the lake was mantained by private body and they have named it has "Fantasy Lagoon".
I heard it for the first time, it may not be a famous as "Lumbini Garden" in Nagavara Lake, but good improvement.
