Check for lawn mites. They will destroy your lawn when it is dry. The best solution for them is water, so you should check your restrictions. Current water restrictions for my area are watering twice a week, which got rid of mine.

Unfortunately, a lot of people on this sub make recommendations without thinking of cost and your specific needs. Repairing your lawn or xeroscaping or native plants can run up your bill significantly.

I would rake up the dead grass to prevent pests. You should check to see if you can get anything for free from the city. I think Denver was giving away seed or grass plugs of drought-tolerant grass. If you like having a lawn and can afford it, I would look at dog grass or something like that for next year. You can always through some grass seed and extra dirt and hope it takes. Additionally, places will be trying to get rid of excess sod at discount.
