    DOCUMENT RESUME ED 058 052 SE 013 121 AUTHOR Reed, David J.; Reid, L slie M. TITLE Outdoor Recreation on Government Lands in Texas, An Analysis. INSTITUTION Texas A and M Univ., C llege Station. Texas Agricultural Experiment Station. REPORT NO B-1081 PUB DATE 1671 NOTE 45p. FDRS PRICE MF-$0.65 HC-$3.29 DESCRIPTORS *Administrative Agencies; Federal Government; *Government (Administrative Body); *Land Use; Natural Resources; *Recreation; Recreational Facilities; Reports; state Government; *Statistical Data IDENTIFIERS Outdoor Recreation; Texas ABSTRACT This study represents an inventory of major government, non-urban outdoor recreation programs and facilities in Texas, as well as an indication of visitor use reported by individual agencies. The purpose of the analysis is to ialustrate the importance of outdoor recreation in Texas and the contribution of various agencies, rather than to determine the quality of recreation programs in the state. Presented first is an examination of outdoor recreation on federal government lands in Texas including those administered by the National Park Service, Bureau of Sport Fisheries and Wildlife, U. S. Forest Service, and U. S. Army Corps of Engineers. Following this is a description of state government lands administered by the Texas Park and Wildlife Department, Texas Forest Service, and Texas River Authorities. Information is also givPn for lakes under jurisdiction of water districts, municipalities, and counties. Numerous tables provide statistics on each area regarding name, location, facility description, recreation opportunities, administering agency, acreage, and 1966 attendance. The data were obtained directly from published reports and records of agencies and generally reflect an accurate description of agency involvement in outdoor recreation.

  • Trophic Classification of Texas Reservoirs
    Trophic Classification of Texas Reservoirs 2016 Texas Integrated Report for Clean Water Act Sections 305(b) and 303(d) The primary productivity of reservoirs, as indicated by the amount of nutrients (phosphorus and nitrogen) and the extent of algae (suspended, floating, and attached) and rooted aquatic plants, can have a significant effect on water quality. Up to a point, nutrients promote ecosystem production and healthy growth of algae, larger plants, and fish and other aquatic organisms. However, excess nutrients and algae in reservoirs can have a deleterious effect on water quality, and algae can reach nuisance levels that potentially (1) create nuisance aesthetic conditions, (2) cause taste and odor in drinking water sources, (3) contribute to reduced dissolved oxygen as algae decay, and (4) and ultimately reduce the ability of a water body to support healthy, diverse aquatic communities. Eutrophication refers to an overall condition characterized by an accumulation of nutrients that support relatively elevated growth of algae and other organisms. Eutrophication is primarily influenced by the physical and hydrological characteristics of the water body and can be affected by natural processes and human activities in the surrounding watershed. Human activities can accelerate the eutrophication process by increasing the rate at which nutrients and organic substances enter impoundments and surrounding watersheds. Discharges of treated sewage, agricultural and urban runoff, leaking septic tanks, and erosion of stream banks can increase the flow of nutrients and organic substances into reservoirs In comparison to natural lakes in northern states, the eutrophication process in southern reservoirs is often enhanced by (1) warm climates with long growing seasons, (2) soils and geologic substrates that create high concentrations of sediment and nutrients in rainfall runoff, and (3) relatively high river inflows on main stem impoundments.
