Elk Slough is a calm, tidal waterway located in the Sacramento-San Joaquin River Delta near Courtland. It is accessible from the Sacramento River, with a common route for power boats being to head downstream from the Clarksburg boat launch to Courtland and then up into Elk Slough. A specific, informal hand-launch site for paddlers is noted near Courtland, a dirt ramp down to the water's edge. The slough's character is defined by its calm water and its banks lined by riparian forests, offering a scenic paddling environment. The broader Delta area, which includes this slough, is known for significant mixed boat traffic, including commercial and recreational powerboats, which is a primary safety consideration for paddlers. The presence of a private boat launch (BW Marina) and the Arrowhead Launch in the general vicinity indicates this is a multi-use recreational area. The waterway is used for exploration and connects to Yolo County, suggesting it is part of a larger network of Delta channels suitable for day trips, such as a journey beginning at the Clarksburg launch.
