16. ABSTRACT

The Bureau of Reclamation surveyed Pueblo Reservoir in April 1993 to compile field data forcomputing a present storage-elevation relationship. The report describes the surveyprocedures and equipment used during the 1993 collection and provides data for futuresurveys. The report also provides results of the investigation to monitor changes caused bysediment accumulation in the reservoir since dam closure on January 9, 1974.

As of May 1993, at reservoir spillway crest elevation (feet) 4898.7, the surface area was 5,671acres, and the total capacity was 349,940 acre-feet. Since the reservoir's initial filling inJanuary 1974, 8,181 acre-feet of sediment have been trapped in Pueblo Reservoir, resulting ina 2.28-percent loss in reservoir capacity. The average annual rate of sediment accumulationsince 1974 is 423.9 acre-feet.

INTRODUCTION

Pueblo Dam and Reservoir, located on the Arkansas River in Pueblo County, are 6 miles westof the city of Pueblo in south-central Colorado. Pueblo Reservoir, formed by Pueblo Dam, isone of the major storage features of the Fryingpan-Arkansas Project. The Fryingpan-Arkansas Project is a multipurpose, transmountain development which diverts water fromthe Fryingpan River and tributaries on the western slope of the Rocky Mountains to theArkansas River on the eastern slope. Additional reservoirs that form the project includeRuedi Reservoir on the western slope and Turquoise Lake, Mt. Elbert Forebay Reservoir, andTwin Lakes Reservoir on the eastern slope. Pueblo Reservoir is the largest and the terminalstorage feature of the Fryingpan-Arkansas project (fig. 1).

Construction of the Fryingpan-Arkansas Project was authorized by Public Law 87-590 (76Stat. 389) and signed by the President on August 16, 1962. Construction of Pueblo Dambegan in 1970 and was completed in August 1975. The left embankment was modified in1980 by the addition of a downstream stability berm to provide protection against potentiallyweak foundation soils. Initial water storage began on January 9, 1974. Maximum elevationwas attained in water year 1986 at reservoir elevation 4887.1 feet.

Pueblo Dam is a composite concrete and earthfill structure, about 10,200 feet long at crestelevation 4925.0. The concrete section has a structural height of 250 feet and a hydraulicheight of 191 feet. The earthifil portions consist of the left and right abutmentembankments, totaling 8,450 feet in length. The concrete dam consists of 23 massive-headbuttresses which total 1,750 feet in length, and has a 550-foot overflow spillway section anda 1,200-foot nonoverfiow section (fig. 2).

The uncontrolled overflow spillway has a crest elevation of 4898.7 feet and is located in theoverflow section of the buttresses. The spillway consists of a concrete ogee crest, trainingwalls, ifip bucket, stilling basin, and an outlet channel. The spillway design flow is 191,500ft3/s (cubic feet per second) at reservoir elevation 4919.0.

Five separate outlets operate at Pueblo Dam. The Bessemer Ditch, located in the rightembankment, is controlled by four high-pressure gates with a maximum discharge of 393ft3/s. The river outlet, located in the buttress over the streambed, is controlled by two gateswith a maximum discharge of 1,120 ft3/s. The spillway outlets, located under the spillway,consist of three gated conduits with a maximum discharge of 8,190 ft3/s. The fish hatcheryoutlet, located in the buttress, is controlled by multilevel gated intakes for controlling waterquality to the downstream fish hatchery. The maximum discharge rate is 30 ft3/s. The southoutlet, located in a buttress, has gated intakes and supplies a maximum discharge of 345 ft3/sof municipal and industrial water (fig. 3).

Pueblo Reservoir has an approximate length of 11.4 miles and an average width of 0.8 milesat reservoir pooi elevation 4900.0. The average width is determined by dividing the surfacearea by the reservoir length at elevation 4900.0. The total Arkansas River drainage areaabove the dam is 4,669 square miles, of which an estimated 4,170 square miles contributes

sediment inflow. The estimated sediment contributing area is the total drainage area minusthe contributing drainage areas above the dams located in the drainage area above PuebloReservoir.

At the beginning of reservoir storage in January 1974, Pueblo Reservoir had a calculatedsurface area of 5,671 acres and a capacity of 357,821 acre-feet at spillway crest elevation4898.7.

SUMMARY AND CONCLUSIONS

This report presents the results of an investigation to monitor changes caused by sedimentaccumulations in Pueblo Reservoir after 19.3 years of reservoir operations. The report alsodescribes the surveying procedures and equipment used in the 1993 investigation andprovides data for future survey use. The primary purpose of the 1993 survey was thecollection of data to compute the area-capacity relationships for operation of Pueblo Reservoir.

Table 1 contains a summary of reservoir sediment data for the 1993 survey. The 1993 surveydetermined'that the reservoir has a storage capacity of 349,940 acre-feet and a surface areaof 5,671 acres at spillway crest elevation 4,898.7. Since closure in January 1974, thereservoir has accumulated a volume of 8,181 acre-feet of sediment below elevation 4,898.7.This volume represents a 2.28-percent loss in total capacity and an average annual loss of423.9 acre-feet for the operating period of January 1974 through May 1993,

DESCRIPTION OF BASIN

The Arkansas River originates in central Colorado and flows in a southerly direction to aboveSalida, Colorado, and then eastward to Pueblo Reservoir. The mean annual runoff of thedrainage basin above Pueblo Reservoir prior to its construction was 511,800 acre-feet. Therunoff was calculated using the 80-year average flow at the USGS (U.S. Geological Survey)gauge Arkansas River near Pueblo, Colorado, which was located about 5 miles downstreamfrom the dam location. The total drainage area above Pueblo Dam is 4,669 square miles, andthe net sediment contributing area is estimated to be 4,170 square miles. The netcontributing area includes removal of areas above the upstream developed reservoirs that areassumed to trap all sediment inflow. The upper Arkansas River is a steep mountain stream,and the basin has about 25 mountain peaks above 14,000 feet. The river emerges from themountainous area through the Royal Gorge, where the valley gradually gets wider throughthe foothills to the plains around Pueblo.

The vegetative cover in the basin above Pueblo is widely diversified because of the wide rangeof annual precipitation. The highest mountain peaks are above timberline and are devoidof cover. In the timber areas, conifers, aspens, brush, and grasses are found. In thewoodland zone, pinon, juniper, scrub oak, sagebrush, and scattered growths of bunch grasspredominate. In the plains region, vegetation consists mainly of grasses, shrubs, andoccasional cactuses. The only trees in the plains region are cottonwood, wifiow, tamarisk, andassociated deciduous trees that fringe the water courses and irrigation ditches.

Wide variations of climate occur in the Arkansas Basin. In the mountainous regions, theprecipitation varies widely over relatively short distances. Much of the total precipitationoccurs in the form of snow. In the plains, most of the precipitation is from rainfall, which attimes occurs in the form of violent cloudbursts, producing small volumes but causing short-

2

duration flash floods of damaging intensities. The recorded annual normal precipitationswithin the watershed vary from 9 to 19 inches. Because of the variation in altitude, themean annual temperatures range from 37 to 54 °F, and the extremes range from -54 to 105°F.

RESERVOIR OPERATIONS

The reservoir is a multiuse facility having (following values are from May 1993 area-capacitytables):

• 131,504 acre-feet of surcharge storage between elevations 4898.70 and 4919.00

• 27,044 acre-feet of flood control storage between elevations 4893.79 and 4898.70

• 65,716 acre-feet of joint use storage between elevations 4880.54 and 4893.79

• 229,059 acre-feet of conservation storage between elevations 4796.70 and 4880.54

• 25,792 acre-feet of inactive storage between elevations 4764.00 and 4796.7

• 2,329 acre-feet of dead storage between elevations 4752.80 and 4764.00

Records for Pueblo Reservoir show a calculated average unregulated inflow of 595,355 acre-feet per year. The estimated mean annual runoff from the basin is 2.06 inches. Since normaloperations have begun, Pueblo Reservoir operation has ranged from a minimum end-of-monthelevation of 4873.4 in water year 1987 to a maximum elevation of 4887.1 in water year 1986.The inflow and end-of-month stage records in table 1 show the extreme annual fluctuationof the reservoir,

SURVEYS

Original Survey

The original sediment ranges were surveyed by the Bureau of Reclamation prior toinundation of water behind Pueblo Reservoir dam and are referred to as the original, or 1974,data. For future reference, Table 3 lists the local and state plane coordinates for the rangeline end points. Several of the ranges had portions of them resurveyed prior to inundationto account for construction borrow pit areas. The finalized original range line data used theresurvey data. Figure 4 illustrates the range line network for Pueblo Reservoir.

The original surface areas for Pueblo Reservoir were determined by planimeteringtopographic maps of the reservoir area developed prior to inundation-Map Numbers 382-706-2270 to 382-706-2290. The topographic maps have a scale of 1 inch equals 400 feet anda 5-foot contour interval. This study used these maps for digitizing the affected segmentedareas as described in the reservoir area and capacity section.

1993 Resurvey

Fieldwork for the 1993 survey began in the spring of 1993. The hydrographic survey wascompleted in late April near reservoir elevation 4859.0. The preliminary field work,performed by personnel from the Eastern Colorado Projects Office and the Pueblo ReservoirOperations Office, consisted of locating and flagging the existing sediment range endmarkers, relocating the destroyed ones, and surveying the range lines not accessible by boat.The hydrographic survey was performed using Reclamation's small boat bathymetric surveysystem. The small boat system consisted of a sonic depth recorder and a reflector prismmounted on the boat. The distances from a known point, usually one of the range endmarkers, to the small boat were determined as the boat proceeded along the range line byan EDM (electronic distance measuring) instrument set up on shore and aimed at themounted reflector target. Range distances were communicated by radio from the shore to theboat at preselected intervals and marked on the sonar charts as the boat proceeded acrossthe reservoir. The boat was held on course as closely as possible by radio communicationfrom the EDM operator to the survey boat. This system was used to collect the underwaterdata for range lines 1 through bA, 20, 21, 30, 40, 41, 42, 50, and 60. The data for rangelines 11 through 16, 43, 51, 61, and 62 were collected by conventional land survey methods.Data were not collected for range lines 17, 18, and 70 because their location was not affectedby previous reservoir operations.

RESERVOIR AREA AND CAPACITY

Development of 1993 Contour Areas

For the purposes of the sedimentation analysis and to better represent storage changes, thereservoir was subdivided into segments, using the range lines to delineate the limit of eachsegmental boundary. The 1993 reservoir surface areas were computed by the widthadjustment method described by Blanton (1982) and illustrated on figure 5. The methodentails computing the new segmented contour area, A1, between ranges by applying anadjustment factor to the original segmental contour area, A0. The computed adjustmentfactor for each segment was the ratio of the new average width to the original average widthfor the ranges, outlining the segment at the specified contour elevation. The input dataincluded the original and 1993 range line data along with the segmented areas for theaffected contour elevations. A comparison of simultaneous plots of original and 1993 rangeprofiles indicated the lateral distribution of sediment at the different measured contourelevations. Where these plots indicate changes have occurred on the side slopes of thereservoir, a decision was made to determine whether the change was caused by actualdeposition, erosion, or survey inaccuracies. No area adjustment was made if the measuredchange was judged to be caused by survey inaccuracy. The 1993 total reservoir surface areaat a given contour is the original total area minus the summation of all segmental areassilted in at that elevation. The 1993 total area computation results are listed in column (2)of table 2.

1993 Revised Storage Capacity

The storage-elevation relationships based on the 1993 underwater survey data weredeveloped using Reclamation's area-capacity computer program ACAP85 (Reclamation, 1985).The 1993 surface areas resulting from the width adjustment computations at 5-foot contourintervals were used as the control parameters for computing reservoir capacity. The program

4

computes an area at 0.01- to 1.0-foot area increments by linear interpolation between thegiven contour intervals. The program begins by testing the initial capacity equation oversuccessive intervals to ensure that the equation fits within an allowable error limit, whichwas set at 0.00000 1 for Pueblo Reservoir. This capacity equation is then used over the fullrange of intervals fitting within this allowable error limit. For the first interval at which theinitial allowable error limit is exceeded, a new capacity equation (integrated from the basicarea curve over that interval) begins testing the fit until it also exceeds the error limit. Thus,the capacity curve is defined by a series of curves, each fitting a certain region of data. Finalarea equations are derived by differentiating the capacity equations, which are of secondorder polynomial form:

y a + a2x + a3x2

where: y = capacity,x = elevation above a reference base,a = intercept, anda2 and a3 = coefficients

Results of the 1993 Pueblo Reservoir area and capacity computations are listed in tables 1and 2 and plotted on figure 6. A separate set of 1993 area and capacity tables will bepublished for the 0.01-, 0.1-, and 1-foot elevation increments (Reclamation, 1993). The 1993area and capacity computations results are listed in columns (4) and (5) of table 2. Column(2) in the table gives the original measured contour areas used in the original area andcapacity computation, and column (3) gives the original capacity computed by ACAP. Boththe original and 1993 area and capacity curves are plotted on figure 6 for a visual comparisonof changes. The 1993 survey determined that the reservoir has a storage capacity of 349,940acre-feet and a surface area of 5,671 acres at spillway crest elevation 4898.7.

SEDIMENT ANALYSES

Sediments have accumulated in Pueblo Reservoir to a total volume of 8,181 acre-feet belowelevation 4898.7, spiiway crest, since storage began in January 1974. This volumerepresents a 2.28-percent loss in total capacity and an average annual accumulation rate of423.9 acre-feet for the 19.3-year period of operation. The net sediment accumulation ratefrom the contributing basin was 0.102 acre-feet per square mile per year for the same period.The measured annual inflow rate is about 41 percent of the original annual. estimate of 1,031acre-feet.

Before projecting future sediment accumulation, the original estimate needs to be reanalyzedusing the John Martin and Pueblo Reservoir sedimentation survey information. John MartinReservoir is located downstream from Pueblo Reservoir and had a net contributing drainagearea of 18,102 square miles prior to Pueblo Reservoir closure in 1974. Ten sediment surveyswere conducted on John Martin Reservoir from April 1942 through March 1972. Thecalculated average annual sediment accumulation between the surveys varied from -0.0398to 0.443 acre-feet per square mile. For the 29.9-year period, the annual sedimentaccumulation rate was 0.148 acre-feet per square mile for the contributing drainage area.A sedimentation survey conducted in June 1980 calculated an annual sediment accumulationrate, from March 1972, of 0.077 acre-feet per square mile for the reduced net contributingdrainage area. The John Martin Reservoir values illustrate the extreme variation of thecalculated annual sediment accumulation values between surveys.

5

It is recommended that an annual rate of 0.130 acre-feet per square mile of contributingdrainage area be used for projecting sediment accumulation in Pueblo Reservoir. This valuewas determined using the 29.9-year annual rate for John Martin Reservoir and the 19.3-yearannual rate for Pueblo Reservoir. This value will be better defined in the future after eachsurvey of Pueblo Reservoir.

The results of the sediment data and volume computations for the 1993 survey are shown intables 1 and 2. The data include a tabulation of incremental sediment inflow volume andsediment accumulation computed for the period between initial conditions and the 1993resurvey. Table 1 includes information on the drainage basin, records of estimated inflow,reservoir operations, and reservoir storage.

RESERVOIR SEDIMENT DISTRIBUTION

Longitudinal Distribution

The distribution of sediment throughout the length of the reservoir is illustrated by plots ofthe thaiweg proffle representing the original and 1993 resurveyed profiles for the ArkansasRiver as shown on figure 7. Thaiweg elevations representing original and resurveyedreservoir conditions were taken from the original and 1993 survey notes. Except for thepossibility of some missed low points, the plotted profile should closely resemble actualchannel bottom conditions during the original range survey completed prior to inundation ofthe reservoir. Except for some minor inaccuracies in sounding and being slightly off line, thebottom of the 1974 and 1993 profiles should closely represent channel bottom conditions atthe time of those resurveys. The channel distance used for range line location is the originalriver channel distance from the dam to each range line in an upstream direction on theArkansas River.

Lateral Distribution

Ground profiles for the 31 original sediment ranges are shown on figures 8 through 38. Thesurvey data were obtained from copies of the original survey data books. Several of the lineshad portions resurveyed prior to reservoir inundation to account for borrow pit areas. Theoriginal data used for the sedimentation analysis accounted for the borrow pit areas. The1993 range profile data are superimposed on these plots to indicate the changes which haveoccurred and to represent in general the lateral distribution of sediment within the reservoir.A 1993 survey was not accomplished for range lines 17, 18, and 70 because they were locatedupstream from elevation 4900.0, and no reservoir deposition was judged to have occurredabove that elevation. For sediment computation purposes, a complete section was needed forall ranges; for this reason, the original data were inserted into the 1993 data file to completethe areas not surveyed in 1993.

47. REMARKS AND REFERENCES

In May 1984, Reclamation recomputed the area and capacity of Pueblo Reservoir using the cubic spline option ofthe Bureau of Reclamation program ACAP. The original surface areas were used as input d ata.

2 Estimated noncontributing area into reservoir. Sediment inflow is affected by several upstream reservoirs suchas Turquoise Lake, Twin Lakes, Clear Creek Reservoir, De Weese Reservoir, and several ot her small res ervoirsand diversion structures.

Calculated inflow to Pueblo Reservoir for water years 1974 through 1993. Runoff contributed by 4,669- square-miledrainage area plus diverted water from the western slope.

Surface area and capacity at spillway crest elevation 4898.7. For sedime nt computation purposes, the originalcapacity was recomputed using the segmented least squares fit option of the Bureau of Reclamation program ACAP.This option is the current method used by Reclamation. The original surf ace areas were used as input data.

1993 surface area and capacity at spillway crest elevation 4898.7. The 1993 area and capacity tables werecomputed using the segmented least squares fit option of the Bureau of Re clamation program ACAP. Thi s optionis the current method used by Reclamation.

6 Maximum and minimum end-of-month reservoir elevations for indicated water years. Calcul ated inflows to PuebloReservoir for indicated water years.
