Construction is set to begin sometime between November and December 2019.
Case says until the construction is completed at Tecumseh, fishermen should plan to use other nearby boat accesses in the area including Bridges Creek (known locally as “Stump Hole” located off County Road 551B, known locally as “Smokey Road”), Udall (on O Highway), Liner Creek (on T Highway) and Calamity Beach (on County Road 24 in Clarkridge, Arkansas).
