Howard Mendall Wildlife Management Area is a 310-acre state-owned salt marsh refuge located on Treat Point between the North Branch of the Marsh River and the Penobscot River in Waldo County. Accessible via river at RM 93.

2 on the Penobscot River Paddling Trail, it offers a good resting and hiking opportunity for paddlers, though access is tide-dependent and best at higher water levels.

The area is notable for its ecological significance as a salt marsh habitat and historical importance, though visitors should be aware of past mercury contamination from industrial activity and coordinate with Maine Department of Inland Fisheries and Wildlife before planning restoration or research activities.
