We appreciate that there’s so much excitement and interest in future recreation at Lake Ralph Hall, and we have seen the questions you’ve shared recently.
Our priority over the last five years has been building the lake and the facilities to deliver water. Knowing how important recreation is to the local area, Upper Trinity is also working to include lake amenities as part of the project: three public access areas, boat ramps, fishing jetty, Ladonia Fossil Park, a trail system and the Visitor Center and Lake Office. The new Ladonia Fossil Park is now open. Other recreation activities will be allowed once the lake is filled (which could take 3-5 years depending on rainfall) and is safe for public use.
We will share information here and on the Lake Ralph Hall website as it becomes available. Please check out our newly updated project FAQ for commonly asked questions on hunting, fish stocking, camping, boat ramps and more: https://lakeralphhall.com/about/faq/.
