After several setbacks, construction on Big Rivers, the water park planned at Grand Texas Sports and Entertainment District, begins in August, CEO Monty Galland said on Tuesday.

The 630-acre complex, located just north of New Caney, is designed to feature a 150-acre theme park, a 40-acre water park, an 83-acre "Sportsplex," a two-mile racing track, an RV park, four hotels and a factory outlet mall.

The theme park portion was initially slated to open summer 2015; then the date was pushed to 2016. It's now slated April 2020 with five roller coasters.
