Dam construction update: starting on June 1, LLELA visitors will not be able to cross the outlet works. There will be no access to the Bittern Marsh Trail or east side of the river. Sometime soon (date currently unknown), all access east of the Cicada Pavilion will be prohibited for about 8 weeks. This will include the following areas and trails: Bittern Marsh Trail, kayaking and fishing in the Elm Fork of the Trinity River, all camping areas, and the Redbud Trail. Only the Blackjack, Green Dragon, Cottonwood, and Cicada Trails will be open during that time.


Research & Restoration


In the North Texas region open space is becoming harder and harder to find. The 2,000 acres known as LLELA is one such place. Set aside for flood control after the construction of the Lewisville Lake dam, this property has been spared from development. It was not, however, spared from prior land use. The land use history includes farming, ranching, and a great deal of soil disturbance during the dam construction that ultimately saved it.

LLELA staff and volunteers work to preserve and restore these 2,000 acres to a functioning ecosystem while providing educational and experiential opportunities to the public such that they have a better understanding and appreciation for the natural heritage that belongs to all of North Texas.

Restoration staff at LLELA are University of North Texas staff.
