Increased ground-water withdrawals associated with the population increase in Island County have caused concern about ground-water availability and potential seawater intrusion. The most widespread and widely used aquifer lies near sea level. Locally, available data also indicate that one or more water-bearing zones lie above the sea-level aquifer. Pumpage in 1979 totaled about 1.67 billion gallons; about 90% was pumped from the sea-level aquifer. Most large producing wells in the county have pumping water levels near or below sea level, so that if pumping continued for a long enough time, seawater intrusion would result. Sampling of chloride concentrations in July 1978, April 1980, and August 1980 indicated problem areas mainly in northeastern and southern Camano Island and in central Whidbey Island. (USGS)
The Satus Creek basin lies on the east flank of the Cascade Range in south-central Washington. The basin is entirely within the Yakima Indian Reservation and is bordered and drained on the east by the Yakima River. Average annual precipitation ranges from about 35 inches in the western upland to less than 10 inches in the eastern lowland. This amounts to a yearly total of about 562,000 acre-feet, most of which falls in the upland. Much of the precipitation falls as snow, and the streamflow from the upland reflects this fact, having a high sustained runoff during the snowmelt months of April, May, and June. In 1973 about 176,000 acre-feet of water was carried by canals for irrigation of about 19,000 acres in the lowland; of this quantity, about 173,000 acre-feet was imported from the adjoining Toppenish Creek basin. This high application rate of about 9.25 acre-feet of water per acre is largely responsible for severe waterlogging problems in many parts of the lowland. Also contributing to the problem are the fine-grained sedimentary deposits that generally overlie the alluvial sand and gravel aquifers in the lowland and retard downward percolation of applied water into those units. In other areas the upward discharge from aquifers in the underlying Yakima Basalt of the Columbia River Basalt Group contributes to waterlogging. Relieving artesiar heads by pumping, combined with reduced application and improved drainage, could alleviate the waterlogging, and free water for use in the irrigation of presently nonirrigated parts of the basin. Young volcanic rocks (basalt) in the southwestern, upland part of the basin appear to contain significant ground-water reservoirs. These rocks receive nearly 70,000 acre-feet a year in recharge from precipitation and, although much of this water is what sustains the high base flows of the streams draining the rocks, the remaining water offers potential for development as a high-altitude source for irrigation water.
The test-observation well drilled near Odessa, Wash., provides information on the area's aquifer characteristics which is not otherwise available from existing deep irrigation wells. The information is of value to the State of Washington Department of Ecology in its management decisions in this area where heavy ground-water withdrawals have resulted in increasing annual water-level declines. The 10-inch well is 750 feet deep and penetrates six aquifer zones (A through F) in basalt. The upper 60 feet of the well is cased while the remainder of the hole is open in the basalt. The well was test pumped during drilling and showed specific capacities of (1) 0.65 gpm (gallon per minute) per foot of drawdown when at the 258-foot depth and open to aquifers A and B. (2) 0.62 gpm per foot of drawdown when at the 540-foot depth and open to aquifers A through D, and (3) 22 gpm foot of drawdown when at full 750-foot depth and open to all six aquifers. To supplement the driller's log of the well, borehole geophysical logging provided information on natural gamma radiation, water temperature and resistivity, downhole movement (via flowmeter) of the water, and borehole diameter (via caliper log). Upon completion of the well each aquifer zone was isolated from the others by cement seals, and piezometer pipes were installed to each zone to allow definition of the vertical hydraulic gradient and an estimate of the vertical ground-water movement in the area, along with chemical-quality sampling of the various zones and monitoring of any changes in water quality with time. The initial measurements of water levels showed that the levels generally decrease with aquifer depth, with about 200 feet of head difference existing between the uppermost and lowermost aquifer zones. Another pipe, installed for providing thermometer access, permits recording the geothermal gradient with depth in the well, and provides another basis for estimating vertical ground-water movement in the area. Prior to isolation of the various aquifer zones, the composite water level was recovering from the cessation of pumping at the end of the 1970 irrigation season. On April 6, 1971, this composite water level had begun declining, presumably as a result of p[umping of an irrigation well 1 mile to the northwest, By May 6, after the aquifer zones had been isolated and piezometer pieces installed, water levels in aquifers E and F had declined 11 feet in 15 days, in response to pumping for irrigation in the area. Water levels in aquifers B, C, and D declined somewhat, but mostly in response to the draining of these aquifers to deeper aquifers down the many deep-well boreholes in the area.
Four anesthetic agents used in human or veterinary medicine and 3 experimental anesthetic preparations were evaluated for effectiveness in inducing narcosis when administered orally to game-farm mallard ducks (Anas platyrhynchos).Tribromoethanol was the only compound to satisfy criteria of initial tests. Mean duration of the induction, immobilization, and recovery periods was 2.4 minutes, 8.7 minutes, and 1.3 hours, respectively, at the median effective dosage for immobilization (ED50; 100 mg./kg. of body weight). The median lethal dosage (LD50) was 400 mg./kg. of body weight.Tribromoethanol was also tested on mallards during the reproductive season. Effects on the hatchability of eggs or the survival of young were not detected.
The response of game-farm mallards (Frost strain) to seven pharmacological immobilizing agents was evaluated in Phase I of a planned four-phase study. A limited amount of testing was also done with wild mallards. Single dosages were administered to determine the mean effective dose (ED50) and mean lethal dose (LD50), The therapeutic index, or safety factor (LD50/ED50), and palatability were also established. Optimum dosage rates of compounds administered orally on baits were not considered in this phase of the study. Compounds were-administered by intubation and calculated in terms of mg/kg. All except one compound produced narcosis within 5 minutes at the effective dose rate.Immobilization periods for the seven compounds ranged from 7-24 minutes, and recovery periods from 1.0-6.5 hours. Such wide variations in actions of the compounds can be attributed to a compound's rate of absorption, the ease with which it passes the blood-brain barrier, its solubility in tissues, and its rate of metabolism in the liver and kidneys. Length of both the immobilization and recovery periods were extended when dosages were increased. There was no delayed mortality among survivors with any of the seven compounds at either the ED50 or LD50. Females were generally more sensitive to the anesthetizing agents than males. The ED50 for wild mallards was substantially higher than that for the experimental game-farm birds for the two compounds on which this was tested.Tribromoethanol (Avertin of Winthrop Laboratories) satisfied all test criteria an Phase I and will be subjected to more intensive investigation in ensuing tests. Thiopental sodium (Pentothal of Amdal Company) and pentobarbital sodium (Nembutal of Abbott Laboratories) were judged to be marginal. Although their therapeutic indexes were good (5.00), recovery periods were prolonged and toxic convulsions occurred at medium to high dose rates as the LD50 was approached.Alpha-chloralose (Fisher Scientific) proved least promising of the seven compounds, mainly because of its unacceptable therapeutic index (2.25) and because it possesses prolonged induction and recovery periods. Two new experimental drugs, methoxymol and metomidate (Pitman-Moore), appeared effective and safe when administered by intubation but produced a taste aversion when added to bait. Rejection because of taste was also a problem with secobarbital (Seconal of Elanco Products), and its therapeutic index of 2.75 was unacceptable. Monitoring of heart and respiratory rates, and body temperature by telemetry showed promise as a technique for determining physiological response to drug action.
