As you can see below, my lawn is a bit of a mess with massive brown sections. My town is on a complete water ban and they are fining anyone running their sprinklers. Hand watering is allowed, but the size of my lawn is a little big for that. The picture below shows just one section. The lawn was originally hydroseeded 3 years ago before I bought the house, so I don't know what type was used. I then overseeded with Black Beauty and a blend from SSS.
What I am trying to figure out though, is why only certain sections are brown. Is it different types of grass? I haven't watered any of it for at least a month, so it isn't like one section is just getting more water. Could something else be causing the brown sections that I can try to fix even without water? The grass there doesn't actually seem dead. It is just brown. If I try to pull some, it still feels like strong grass in the sense that it doesnt pull from the lawn easily.

Is this just a matter of needing to water everything? My best guess is that the brown parts are a different type of grass that browns in the summer time. At least if that is the case I can know to try and fix that part of it.
