[2][3] [T]he park was established about a decade after the U.S. Army Corps of Engineers built 29,500-acre Millwood Lake north of Texarkana in Miller County.

Held in place by a 3.3-mile-long earthen dam (the longest of its type in Arkansas), the lake’s trademark timber stands have made it a bass-fishing haven by providing cover vegetation and a food source that keep the fish in shallow, more accessible water.

[4] Among several recreational areas the Corps of Engineers established on the lake’s shoreline was Cypress Slough, at the southwestern end of Millwood Dam.

[4] Due to the Corps of Engineers’ involvement, a combination of state and federal funds was used to expand the park’s facilities.

[4]The park offers camping and picnicking sites, hiking and bike trails, marina with boat rentals, and interpretive activities.
