Aurora Water is in talks to purchase land and water from two of the most historic farms in the Lower Arkansas Valley, adding to farm communities’ worries about “buy and dry” pressure from cities amid historic drought and a dwindling agricultural economy. But Aurora Water says it has learned lessons from past controversies and is structuring the latest buy-up to preserve southeastern Colorado farm life, not destroy it. … Recent southeastern Colorado water purchases by Aurora Water and other utilities have given the agencies rights to dry up farmland in, for example, three out of 10 years. Many local farmers and water conservancy officials say that casts too much uncertainty on a farm owner’s economic plans. They are also not convinced that farmland can recover after being completely dried up for entire seasons.
