40-50 years ago most people of modest resources could afford to keep a weekend cabin on one of the central Texas lakes and very few folks lived in permanent residences on the lake. Massive taxes, better roads, bridges, and extreme population influxes with the advent of high tech industry in the area have pretty much limited peoples ability to afford secondary residences on the lakes. Now, most lake homes are primary residences.
No one uses the term much anymore except when the tourists are out on holiday weekends. During those periods a "RiverRat" keeps his boat wound to the top of the boat lift and wouldn't get near the water.
