Blackwater Creek flows from Lake Norris through Seminole State Forest to the Wekiva River, joining the Wekiva not far from where that waterway meets the St. Johns River.
The upstream end can be paddled in kayak or canoe from the Lake Norris Conservation Area into Lake Norris, but usually requires negotiating over fallen trees. The lower portions of Blackwater Creek can be paddled by entering it from the Wekiva River.
Read my blog post on kayak photography which includes a mention of the other kayaker I meet on the creek the day I photographed Blackwater Creek Palms and a link to his blog.
These palm trees are cabbage palms.
