The 2020 TWDB volumetric survey indicates that Lake Texana has a total reservoir capacity of 164,188 acre-feet and encompasses 10,312 acres at conservation pool elevation (44.0 feet NGVD29). Current area and capacity estimates are compared to previous area and capacity estimates at different elevations in Table 3.

The 2010 TWDB sedimentation survey indicates Lake Texana has accumulated 11,462 acre-feet of sediment since impoundment in 1980. Based on this measured sediment volume, Lake Texana lost an average of approximately 382 acre-feet of capacity per year from 1980-2010. Sediment accumulation is greater in the lower half of the lake.

The 1994 survey determined that the reservoir has a total storage capacity of 741,594 acre-feet and a surface area of 19,602.5 acres at water surface elevation 4725.0. Since closure in October 1951, the reservoir has accumulated an estimated volume of 78,171 acre-feet of sediment below elevation 4725.0.

Methods Summary. A complete bathymetric survey was conducted during May 2018 from an 18-foot aluminum boat using a multibeam depth sounder to continuously measure water depths. The horizontal position of the moving boat was continually tracked using RTK GPS. A map of the data points collected is presented in Figure 6.

Sedimentation Survey Abstract Reclamation's Sedimentation Group surveyed Lake Mead in spring 2001 to develop a storage-elevation relationship. This report was produced by the Sedimentation Group summarizes the 2001 Lake Mead survey results that utilized reconnaissance procedures for collection and analysis (Ferrari, 2006). The 2001

USACE adaptation pilots identified altered reservoir sedimentation rates that result from a changing climate and land use change as a critical area for agency missions and operations. USACE is the largest operator of dams in the United States. Each USACE dam was planned, designed and built to provide specific benefits to the American public ...

The purpose of this report is to describe and document the USGS sedimentation survey conducted at Lago de Cidra during August 2007, including the methods used to update the reservoir storage capacity, sedimentation rates, and areas of substantial sediment accumulation since 1997. ... 2010: Language: ENGLISH: Publisher: U.S. Geological …

During September–November 2012, the U.S. Geological Survey, in cooperation with the Puerto Rico Aqueduct and Sewer Authority, conducted a sedimentation survey of Lago Caonillas to estimate current (2012) reservoir storage capacity and the recent (2000–2012) reservoir sedimentation rate by comparing the …

Reservoir sedimentation is a serious challenge that reduces reservoir life. Because it decreases the initial capacity of the reservoir and has an impact on drinking water supply, irrigation, and hydropower activities. Inadequate land activities and poor management techniques cause soil erosion and reduce reservoir storage capacity. As a …

The U.S. Geological Survey conducted a sedimentation survey of Lago Lucchetti, Yauco, Puerto Rico, in 2013–14 in cooperation with the Puerto Rico Aqueduct and Sewer Authority. The survey updated a previous survey, conducted in 2000, and provided accurate information regarding reservoir storage capacity and sedimen­tation rate using …

The USGS, in cooperation with the Government of Puerto Rico, has conducted sedimentation surveys since 1994 in 14 reservoirs used for domestic and industrial water supply, power generation, and irrigation. A GPS, a survey-grade echo sounder, and GIS, were used to plan, collect, and analyze hydrographic data to …

The inter-survey sedimentation rate between 1997 and 1999, however, is higher than the long-term rate at about 1.09 million cubic meters per year. Between 1999 and 2005 the rate is lower than the long-term rate at about 0.13 million cubic meters per year. ... which is much lower than the 1942-1997 area normalized sedimentation rate of …
