I caused the end of a drought about a dozen years ago. I was doing a big deck build and back yard makeover, and put in an 1100 gallon HDPE tank and piped downspouts into it. Installed an irrigation pump, mostly drip irrigation. Decent capital investment. Did it to side step outdoor water use restrictions during the drought.
The skies opened up, the reservoirs filled, the water use restrictions ended.
In addition to the sodding I had done, I have a 22’ square patio deck, that also collects some roof water, that would flood an area and wash away the bare soil under one of the Bradford Pears, even in moderate rain. This bare area is now sodded. The deck gutter system was cleaned out and downspouts installed into plastic underground pipe carrying away the runoff.
It has not rained since. Mother Nature can be a you-know-what lol
