Located in the heart of downtown Midland, MI, Dow Diamond was first opened to professional baseball on April 13, 2007 when the home team Great Lakes Loons lost 6-2 to the Lansing Lugnuts. Dow Diamond is named in honor of the Dow Chemical company which is headquartered in Midland and bought the naming rights in the winter of 2006. Dow Diamond was built on land donated to the Michigan Baseball Foundation by Dow Chemical, and the crushed red brick that makes up the warning track is made from the bricks that built the Dow plant that once occupied the location. The park, like the Loons, is owned and operated by the non-profit Michigan Baseball Foundation.

Dow Diamond feels very natural to be located in northern mid-Michigan. When enterring the stadium, one must first ascend a flight of stairs which is framed with a riverstone facing. At the top of the stairs is the main concourse. immediately to the left is the "Loon Loft" the Great Lakes Loons' two story team store. River rock facing is again used to accent the entrance to the luxury loft suites which make up the second level of the park. situated in this rock face, directly behind home plate is the first of three fireplaces which add ambience to the park. The other two fireplaces are large round brick and stone firepits which are situated amongst the lawn seating in right-center and left-center field. On chilly nights in the early and late parts of the season, crowds gather around the fireplaces making them uniquely popular features for fans. Dead center field is sectioned off from fans. This section of the park features a large garden with a unique feature: a large nest, possibly the home of the team's mascot Lou E. Loon.
Dow Diamond is intimately connected to the Dow Chemical Company in more than just name. Dow Diamond features a very large and unique children's play area called Lou E.'s Loft. Both the playground and the flooring (which features a large map of Michigan) are made from Dow Polyurethane Systems. Dow also constructed a large set of Solar panels which sit just outside the park, visible from both the parking lot and the concourse in right field. These Solar panels generate power for the scoreboard at Dow Diamond.
