Lake Lowell Park

Story Trail Closed for Construction (June-July 2024)

The Story Trail at Lake Lowell Park will be closed during June and July 2024, while crews make improvements to the trail and surrounding landscaping. Please respect closed areas, which will be marked with traffic cones as well as signs posted at Story Trail entrances. We are working on more efficient irrigation infrastructure and planting new drought-resistant and pollinator-friendly shrubs and trees. Thank you for your patience during this temporary closure!

Built by the Bureau of Reclamation to provide irrigation water for Canyon County agriculture, Lake Lowell opened in 1909 and is one of the largest off-stream reservoirs in the American west, with the capacity to irrigate over 200,000 acres of land. It has also become a popular recreation destination for the county’s citizens and visitors. Boating, swimming and fishing are among the many activities that folks enjoy at this beautiful oasis in southwest Idaho. Bird watching, hiking and hunting are other recreation options due to the presence of the U.S. Fish and Wildlife’s Deer Flat National Refuge, also established in 1909. As part of the wildlife refuge, recreation on Lake Lowell’s shoreline and waters may be subject to seasonal restrictions.

Motorized and Non-motorized boating are allowed April 15 to September 30. Human-powered boats are allowed 200 yards in front of the Upper and Lower Dams between October 1 and April 14. The rest of the lake is set aside for migrating and wintering wildlife.

Year round, dawn until dusk.
There are no day-use fees at this park.
The address for Lake Lowell Park is 12996 Iowa Ave. in Nampa.

The Story Trail at Lake Lowell Park was created by Canyon County Parks in 2012. From May through October, a different story book is displayed each month on reading platforms located along a nature trail in the park. Visitors can wander the trail and read fun, nature-related stories while exploring the park. It provides another way for families to be outside and, at the same time, reinforce the joy of reading! The Story Trail and Lake Lowell Park are open from dawn to dusk, every day.
