Texas parks officials have scheduled a series of news conferences across the state to address what they say is an urgent situation facing the public parks.
No details were released in advance of Tuesday's first announcement at McKinney Falls near Austin.
Texas parks officials have noted that the state's severe drought and burn bans across most of the state have driven down attendance. Fewer visitors would mean less revenue for the parks system.
Wildfires have been another problem. A Labor Day fire turned much of Bastrop State Park's picturesque Central Texas hills into a blackened sea of torched pine trees.
Researchers say the drought has depleted Texas aquifers to some of the lowest levels in 60 years and is likely to continue for several months.
