Geothermal leak halted, Boise’s Military Reserve park back open

The Military Reserve park is about 460 acres, and Boise officials want recreationists to be careful in that area, especially around water, due to a geothermal leak.
The Military Reserve park is about 460 acres, and Boise officials want recreationists to be careful in that area, especially around water, due to a geothermal leak.

Crews have isolated and shut off a geothermal line that ruptured in the area and Military Reserve has largely reopened, the city of Boise confirmed Friday afternoon.

An area around the rupture where geothermal water pooled — just north of the archery range — will remain closed into next week when repairs will be completed.

The city earlier Friday had closed the entire park over concerns that the leaking water could be in ponds and streams, endangering the public. The city was still determining the scope of the leak at that point.

The Military Reserve is managed by the city and covers about 450 acres surrounding Fort Boise.

This isn’t the first time Boise residents have needed to take caution in the Boise Foothills due to geothermal activity. In 2014 a hot springs overflow near the Table Rock trail head parking lot led to the death of a Boise woman’s dog.
