Napa Valley Paddle and High Water Stand Up Paddle have merged businesses. The company is now known as Napa Valley Paddle.
The business owners are Bailie Heather and Andrew Dickson.
"This is a natural fit between two companies," said a news release.
Napa Valley Paddle offers stand-up paddle board and kayak rentals, paddle fitness, river tours and fishing excursions.
In addition, a pop-up paddle shop within Napa River Velo on the Riverfront will open May 1.
The company has also partnered with the Resource Conservation District and the Flood Control District to host "conservation excursions" where paddlers can volunteer to clean up and remove invasive plants from the river bypass.
