Drought.gov actually keeps track of that! For example for New Hampshire: https://www.drought.gov/states/new-hampshire https://www.drought.gov/states/new-hampshire Scroll down to the graph, click "1895 - Present (Monthly)", and click the different levels of exceptional drought/exceptional wetness. You can see that NH has been trending wetter for the last 100 years (as with all the northeast), more or less the opposite of the southwestern US. Large periods of exceptional wet have happened in my life, with fewer big droughts than ever. (Alas, we're in a drought right now.) You can also see that California had some unusually wet periods in the 80's and 90's, which might have informed policy, but were simply an anomaly: https://www.drought.gov/states/california https://www.drought.gov/states/california
