Greetings. We are building a home in NE Kansas this Fall/Winter/Spring and are debating on having a pond dug as part of the construction process. We WANT to, but don't want to have an empty hole for more five or more years either. With that, what is your precipitation prediction for NE Kansas for 2020-2023? Thank you!
