Sevier County municipalities have sufficient underground culinary water rights to support a population of 44,000, about 21/2 times the current county population.
But there is less water available for expansion in the larger cities than in the small towns, according to a Utah Division of Water Resources inventory titled Municipal and Industrial Water Use Inventory. The combined water sources in the county contain 9,921 acre feet.Richfield is the largest city in the county with about 7,000 population, and the projection of available underground water would supply only about 10,750 people, or a 55 percent increase. On the other hand, Sigurd, with a current population of about 400, would have enough water for a population of nearly 4,000, allowing a 10 fold increase.
Salina, the second largest city in Sevier County, has sufficient underground water for an 83 percent population gain to just over 4,000. The current population is about 2,200. Available water for Monroe, the third largest city with a population of 1,606, could support a greater population increase than the other two cities, or just over three times the present population.
Overall, the available water in Sevier County is about 9,921 acre feet.
