Watsadler on US 29 on the Geogia side of the dam. Springfield in SC (forgot the town and hiway number) near the dam. Both are very nice. Tugaloo is OK, but the locals think they own the place, especially the peninsula with the best sites. Hart SP in Hartwell city is nice, and even has some FHU sites.
The Savannah River runs from NC, bordering SC and GA, and flows to the Atlantic ocean. Between the mid forties through the mid eighties, the COE built three big dams on the river for hydroelectricity, flood control, and navigation. IIRC, three big lakes; Hartwell, Mitchell, and Strom Thurmond were created and there are lots of COE and State Parks, as well as County/City parks, to choose from.
US Campgrounds is a very good website I've used to locate those parks. The GA/SC State parks are reasonably priced, as are the County/City parks. Of course, the "geezer" pass at the COE's trumps them all.
My grandfather help build the dam at Strom Thurmond (real name is Clarks Hill Lake...lol)
To answer part of your question, yes you can fish from the bank. swimming will be at your own risk. While many people do it, I will tell you there are a good bit of snakes in the Savannah River area.
Also, on the fishing part, you will need to purchase a non-resident license from either SC or GA. Both states have a reciprocal agreement and you can fish in those lakes from boat or shoreline with either states license. Get it from SC. The SC nonresident 7 day license is only $11. GA has a 3 day non resident for $20.

Thanks, I was curious if you could do that because a lot of times "fishing holes" that are on the bank of lake and ponds are covered with tangled broken fishing lines, lures and hooks.
I imagine it might be the same at Hartwell (been many moons since I've been there) as it is at Clarks Hill (Strom Thurmond), but some things will vary upon the campground and the water level of the lake. My inlaws own a home (for sell by the way for a measley $995,000 - message me if interested...lol) on Clarks Hill and the COE releases water out of the damn sometimes at a rate that will really affect the water level. At or near full pool, it's awesome, but then there are times that the level will drop that the shoreline will be a drop off of several feet. Also, accessibility to the shoreline from your campsite will vary as well. It will be hard to tell you if your site is accessible, except if someone has stayed at it before. It may be accessible, but some climbing/sliding may be involved.
