| 465: | | Title: | | | | | Volume/Number: | 1962 | | | | Issuing Agency: | | | | | Description: | The practical application of selected analytical methods to well and aquifer evaluation problems in Illinois is described in this report. The subject matter includes formulas and methods used to quantitatively appraise the geohydrologic parameters affecting the water-yielding capacity of wells and aquifers and formulas and methods used to quantitatively appraise the response of wells and aquifers to heavy pumping. Numerous illustrative examples of analyses based on actual field data are presented. The aquifer test is one of the most useful tools available to hydrologists. Analysis of aquifer test data to determine the hydraulic properties of aquifers and confining beds under nonleaky artesian, leaky artesian, water table, partial penetration, and geohydrologic boundary conditions is discussed and limitations of various methods of analysis are reviewed. Hydraulic properties also are estimated with specific-capacity data and maps of the water table or piezometric surface. The role of individual units of multiunit aquifers is appraised by statistical analysis of specific capacity data. The influence of geohydrologic boundaries on the yields of wells and aquifers is determined by means of the image-well theory. The image-well theory is applied to multiple boundary conditions by taking into consideration successive reflections on the boundaries. Several methods for evaluating recharge rates involving flow-net analysis and hydrologic and groundwater budgets are described in detail. Well loss in production wells is appraised with step-drawdown test data, and well screens and artificial packs are designed based on the mechanical analysis of the aquifer. Optimum well spacings are estimated taking into consideration aquifer characteristics and economics. Emphasis is placed on the quantitative evaluation of the practical sustained yields of wells and aquifers by available analytical methods. The actual groundwater condition is simulated by a model aquifer having straight-line boundaries, an effective width, length, and thickness, and sometimes a confining bed with an effective thickness. The hydraulic properties of the model aquifer and its confining bed, if present, the image-well theory, and appropriate groundwater formulas are used to construct a mathematical model that provides a means of evaluating the performance of wells and aquifers. Records of past pumpage and water levels establish the validity of this mechanism as a model of the response of an aquifer to heavy pumping. | | | | Date Created: | 9 24 2004 | | | | Agency ID: | B-49 | | | | ISL ID: | 000000000733 Original UID: 999999992049 FIRST WORD: Selected | |
| 466: | | Title: | | | | | Volume/Number: | 1999 | | | | Issuing Agency: | | | | | Description: | The Illinois State Water Survey, in cooperation with the Consumers Illinois Water Company (CIWC), conducted a sedimentation survey of Lake Vermilion during the summer of 1998. The survey was undertaken to provide information on the storage and sedimentation conditions of the lake following a 1991 increase in the operational lake level. Lake Vermilion is owned and operated by the CIWC. The CIWC withdraws water from Lake Vermilion as the sole raw water source for direct distribution of finished water to Danville and Tilton, Illinois. The CIWC also provides finished water to the Catlin and Westville public water supplies. Lake Vermilion is located in Vermilion County, one mile northwest of Danville, Illinois. The operating elevation for the reservoir was increased from 576 feet NGVD to 582.2 feet NGVD in 1991. This modification increased storage capacity of the lake by approximately 4,600 acre-feet (ac-ft). Analysis of sedimentation rates for this larger storage capacity required the introduction of the term potential capacity for the reservoir for 1925-1991. The potential reservoir capacity was defined as the capacity of the reservoir if the basin formed by the valley had been filled to the level of the 1991 spillway. Sedimentation has reduced the potential capacity of Lake Vermilion from 13,209 ac-ft (4,304 million gallons) in 1925 to 7,971 ac-ft (2,597 million gallons) in 1998. The sediment accumulation rates in the lake have averaged 71.8 ac-ft per year from 1925-1998. Annual sedimentation rates for three separate periods, 1925-1963, 1963-1976, and 1976-1998 were 89.5, 50.2, and 53.9 ac-ft, respectively. Earlier lake structures affect the lake as it exists in 1999. These early structures also affected the ability to analyze the present sedimentation rate. The 1914 structure (the old dam) impounded water in what is now the upstream, northern half (lengthwise) of the present lake. This structure caused an undocumented amount of sedimentation in the affected lake segments. This sedimentation is included in the calculated sedimentation volume for the 1925-1963 survey period. On the basis of a 38-year (1925-1963) or a 49-year sedimentation period (1914-1963), the average annual sedimentation rate for the lake would be 89.5 and 69.4 ac-ft per year, respectively. Either rate is considerably higher than subsequent rates. The adjustment of the earlier volumes included an accounting of above water-level deposits for the 1963 and 1976 survey calculations and slightly increased the reported sediment volumes for those surveys. The change in reference capacity also significantly altered the presented sedimentation rates in percent of original volume. | | | | Date Created: | 8 31 2006 | | | | Agency ID: | CR-643 | | | | ISL ID: | 000000000799 Original UID: 999999994049 FIRST WORD: Sedimentation | |
| 467: | | Title: | | | | | Volume/Number: | 1999 | | | | Issuing Agency: | | | | | Description: | The Illinois State Water Survey conducted a sedimentation and hydrographic survey of three small lakes at The Morton Arboretum in Lisle, Illinois, during the summer of 1998. The survey was undertaken in support of an Illinois Clean Lakes Program diagnostic/feasibility study of the lakes. The lakes are owned and maintained by The Morton Arboretum and serve primarily as landscape accents on the grounds. The lakes surveyed were: Meadow Lake, constructed in 1960; Sterling Pond, constructed in 1963; and Lake Marmo, constructed in 1922. Lake sedimentation occurs when sediment-laden water enters the reduced flow velocity regime of a lake. As the water velocity is reduced, suspended sediment is deposited in patterns related to the size and fall velocity of each particle. The soil particles are partially sorted by size along the longitudinal axis of the lake during this process. Larger, heavier sand and coarse silt particles are deposited in the upper end of the lake; finer silts and clay particles tend to be carried further into the lake. A sedimentation survey is a measure of the rate of volume and/or depth loss of the reservoir. The sedimentation survey provides detailed information on distribution patterns of sediment within the lake as well as temporal changes in overall sedimentation rates. Sedimentation has reduced the capacity of Meadow Lake by 10 percent, Sterling Pond by 51 percent, and Lake Marmo by 29 percent. The sediment accumulation rates in the lakes averaged 0.10 acre-feet per year for Meadow Lake, 0.29 acre-feet per year for Sterling Pond, and 0.10 acre-feet per year for Lake Marmo. | | | | Date Created: | 3 21 2006 | | | | Agency ID: | CR-638 | | | | ISL ID: | 000000000806 Original UID: 999999994113 FIRST WORD: Sedimentation | |
| 468: | | Title: | | | | | Volume/Number: | 2001 | | | | Issuing Agency: | | | | | Description: | Sedimentation detracts from the use of any water supply lake by reducing lake depth and volume, with a reduction of reserve water supply capacity and possible burying of intake structures. Sedimentation of a reservoir is a natural process that can be accelerated or slowed by human activities in the watershed. Silver Lake is Located in Madison County, one mile northwest of Highland, Illinois. The location of the dame is 38 degrees 46' 00" north latitude and 89 degrees 42' 05" west longitude in Section 30, T.4N., R.5W., Madison County, Illinois. The dam impounds the East Fork of Silver Creek, a tributary of Silver Creek in the Kaskaskia River basin. The watershed is a portion of Hydrologic Unit 07140204 as defined by the U.S. Geological Survey. Construction of the lake was completed in 1962. The Silver Lake watershed consists of the 47.1-square-mile area drained by the East Fork of Silver Creek above the dam site. Land use in the watershed of the lake is mainly agricultural. Average annual precipitation in the area is 38.98 inches as measured at Greenville (1961-1990), and the average runoff (1912-1998) is approximately 10.0 inches (Shoal Creek near Breese). Average annual lake evaporation rates are 35.2 inches per year at St. Louis, Missouri. The Illinois State Water Survey conducted sedimentation surveys of Silver Lake in 1981 and 1984. In 1981, cross sections were laid out at 14 lines across the lake and surveyed. Sedimentation surveys of Silver Lake in 1984 and 1999 repeated as closely as possible the series of survey lines established during the 1981 survey. Sedimentation has reduced the capacity of Silver Lake from 7,322 acre-feet or ac-ft (2,386 million gallons) in 1962 to 5,832 ac-ft (1,900 million gallons) in 1999. Sediment accumulation rates in the lake have averaged 40.3 ac-ft per year from 1962-1999. Annual sedimentation rates for three separate periods, 1962-1981, 1981-1984, and 1984-1999, were 51.2, 63.0, and 21.9 ac-ft, respectively. Density analyses of the sediment samples indicate that sediment in the northern (upstream) portions of the lake has greater unit weight than sediment in the southern end of the lake. In general, coarser sediments are expected to be deposited in the upstream portion of a lake where the entrainment velocity of the stream is reduced to the much slower velocities of a lake environment. These coarser sediments tend to be denser when settled and are subject to shallow drying and higher compaction rates as a result of more frequent drawdown exposure in the shallow water environment. As the remaining sediment load of the stream is transported through the lake, increasingly finer particle sizes and decreasing unit weight are observed. The sedimentation rate for Highland Silver Lake is similar to the rates for other Illinois lakes of similar size and character. The sedimentation for Silver Lake is in the low to average ranged compared to other Illinois lakes. | | | | Date Created: | 9 24 2004 | | | | Agency ID: | CR-2001-05 | | | | ISL ID: | 000000000835 Original UID: 999999994316 FIRST WORD: Sedimentation | |

Sedimentation of a reservoir is a natural process that can be accelerated or slowed by human activities in the watershed. Lake Decatur is located in Macon County, northeast of Decatur, Illinois. The location of the dam is 39 49 28" north latitude and 88 57 30" west longitude in Section 22, T.16N., R.2W., Macon County, Illinois. The dam impounds the Sangamon River in the Sangamon River basin. The watershed is a portion of Hydrologic Unit 07130006 as defined by the U.S. Geological Survey. The lake was constructed in 1922 with a spillway level of 610 feet above mean sea level (feet-msl). In 1956, a set of hydraulic gates was installed on the original spillway to allow variable lake levels from 610 feet-msl to 615 feet-msl. The portion of the lake surveyed for the present study was Basin 6 located above Rea's Bridge Road. This basin of the lake is the headwater area of the main body of the lake. Lake Decatur has been surveyed to document sedimentation conditions eight times since 1930. Five of these survey efforts (1936, 1946, 1956, 1966, and 1983) were sufficiently detailed to be termed full lake sedimentation surveys. The present survey is not considered to be a full lake sedimentation survey. Sedimentation has reduced the basin capacity from 2,797 acre-feet (ac-ft) in 1922 to 1,451 ac-ft in 2000. The 2000 basin capacity was 48.1 percent of the 1922 potential basin capacity. For water supply purposes, these volumes convert to capacities of 911 million gallons in 1922 and 473 million gallons in 2000. Sedimentation rate analyses indicate a decline in annual sediment deposition rates from 35.4 ac-ft for the period 1922-1936 to 8.3 ac-ft annually from 1983-2000. The long-term average annual deposition rate for 1922-2000 was 17.3 ac-ft. Density analyses of the sediment samples indicate that the unit weight of sediment in the northern (upstream) portions of the lake is greater than the unit weight of sediment in the southern end of the lake.

The portions of the lake surveyed for the present study were the Big and Sand Creek basins. These basins are the two major tributary stream basins formed to the south (Sand Creek) and east (Big Creek) of the main body of the lake. They receive the flow of Sand, Big, and Long Creeks. Lake Decatur has been surveyed to document sedimentation conditions nine times since 1930. Five of these survey efforts (1936, 1946, 1956, 1966, and 1983) were sufficiently detailed to be termed full lake sedimentation surveys. The survey discussed in detail in this report is not a full lake sedimentation survey. However, additional work included in the present study could be combined with the 2000 survey of Basin 6 of Lake Decatur to provide a complete baseline survey for future reference. Sedimentation has reduced Big Creek basin capacity from 2,754 acre-feet (ac-ft) in 1922 to 1,512 ac-ft in 2001. The 2001 basin capacity was 54.9 percent of the 1922 potential basin capacity. For water-supply purposes, these volumes convert to capacities of 897 million gallons in 1922 and 493 million gallons in 2001. Sedimentation rate analyses indicate a decline in annual sediment deposition rates from 28 ac-ft (1922-1946) to 9.9 ac-ft annually (1983-2001). The long-term average annual deposition rate was 15.7 ac-ft (1922-2001). Sedimentation has reduced the Sand Creek basin capacity from 610 acre-feet (ac-ft) in 1922 to 246 ac-ft in 2001. The 2001 basin capacity was 40.3 percent of the 1922 potential basin capacity. For water-supply purposes, these volumes convert to capacities of 199 million gallons in 1922 and 80 million gallons in 2001. Sedimentation rate analyses indicate a decline in annual sediment deposition rates from 8.4 ac-ft (1922-1946) to 2.3 ac-ft annually (1983-2001). The long-term average annual deposition rate was 4.6 ac-ft (1922-2001). | | | | Date Created: | 9 24 2004 | | | | Agency ID: | CR-2002-09 | | | | ISL ID: | 000000000870 Original UID: 999999994347 FIRST WORD: Sedimentation | |
| 471: | | Title: | | | | | Volume/Number: | 2003 | | | | Issuing Agency: | | | | | Description: | The Illinois State Water Survey (ISWS) conducted sedimentation surveys of Lake Paradise and Lake Mattoon during 2001 in support of an Illinois Clean Lakes Program diagnostic/feasibility study to provide information on the storage and sedimentation conditions of the lakes. Both lakes are owned and operated by the City of Mattoon, which withdraws water from Lake Paradise as the raw water source for distribution of finished water and generally uses withdrawals from Lake Mattoon to maintain a more stable water level in Lake Paradise. The village of Neoga also withdraws water from Lake Mattoon for treatment and distribution. Since June 2001, Reliant Energy has operated a peaker power plant that has withdrawn water from Lake Mattoon for cooling systems. Lake Paradise and Lake Mattoon are located on the main stem of the Little Wabash River, a tributary to the Wabash River. The watershed is a portion of Hydrologic Unit 05120114. The dam for Lake Paradise is about 4 miles southwest of the City of Mattoon at 39 24' 47" north latitude and 88 26' 23" west longitude in Section 8, Township 11N., Range 7E., Coles County. The dam for Lake Mattoon is about 12 miles southwest of the City of Mattoon at 39 20' 00" north latitude and 88 28' 56" west longitude in Section 1, Township 10N., Range 6E., Shelby County.Lake Paradise was surveyed in 1979 and Lake Mattoon in 1980 as part of a previous cooperative study by the ISWS, the Illinois Department of Transportation - Division of Water Resources (DoWR), the Illinois Water Resources Center, and several departments at the University of Illinois at Urbana-Champaign. Lake Paradise lost 835 acre-feet (ac-ft) of its capacity as a result of sedimentation between 1908 and 2001. Approximately 481 ac-ft of this loss has occurred since 1931, which gives an annual sedimentation rate of 9.9 ac-ft since 1931. If this rate of sedimentation continues, the volume of Paradise Lake will be approximately half of the potential 1908 volume in the year 2013 and will be filled completely by sediment in the year 2118. Lake Mattoon lost 1,705 ac-ft of its 1958 capacity as a result of sedimentation between 1958 and 2001, a sedimentation rate of 39.7 ac-ft per year since 1958.If this rate of sedimentation continues, the volume of Lake Mattoon will be approximately half of the 1958 capacity by 2124 and will be completely filled in the year 2291. The sedimentation rates for Lake Paradise and its watershed for the periods 1931-1979, 1979-2001, and 1931-2001 were stable and ranged from 9.5 to 10 ac-ft.The long-term average annual sediment yield from 1931-2001 was 9.85 ac-ft. These sedimentation rates correspond to a rate of loss of lake capacity of 0.51 percent per year (1931-2001). The sedimentation rates for Lake Mattoon and its watershed for the periods 1958-1980, 1980-2001, and 1958-2001 indicate a reduction in net sediment yield from 66.9 ac-ft per year for 1958-1980 to 10.7 ac-ft per year (1980-2001).The long-term average annual sediment yield was 39.5 ac-ft (1958-2001). These sedimentation rates correspond to rates of loss of lake capacity of 0.51 percent per year (1958-1980) and 0.08 percent per year (1980-2001).The long-term average sedimentation rate for the lake is 0.30 percent per year (1958-2001). | | | | Date Created: | 9 24 2004 | | | | Agency ID: | CR-2003-04 | | | | ISL ID: | 000000000881 Original UID: 999999994353 FIRST WORD: Sedimentation | |
