A total of 16 beds are in place at the Mini-Cassia Juvenile Detention Center. It is operated by the Minidoka County and Cassia County as a joint venture and allows each to access the beds they need for their juvenile offenders or others, without the responsibility falling only on one county.
This shared expense provides a better facility that is safer and more secure than either could provide on their own. The purpose of the facility is to house juveniles for their own safety or for the safety of their community, to ensure that juveniles facing charges will appear at their court dates, and to house juveniles with an option for serving their sentence.
It uses a highly structured routine each day to ensure that the safety within is protected, and to encourage responsibility and discipline as well as meeting the basic needs of housing, food, education, medical care, hygiene, and rest. Recreational spaces and activities are provided. It is the responsibility of parents to deliver and pick up any school assignments, and youth will be provided with adequate time to complete all assignments.
Mail: Letters are permitted to be sent and received with friends and family, and the facility will pay for the postage for the first five letters for each student every week.
Phones: Students are provided time and access for three phone calls each week, either incoming or outgoing, and they are only allowed to call or receive calls from parents, grandparents, or legal guardians.
Visitation: Parents, guardians, or grandparents may visit each week and are preapproved for visits. The visiting times are Sundays 2:30-4:30pm and Wednesdays 7-8pm
