Tables 111 through 114. These four sites produced flow in 1991 but <br />• did not flow in 1990. <br />Over half of the ponds had no measurable discharge in 1991 although <br />all of the ponds discharged in 1987. In addition, the discharge in <br />Steven's Gulch at station SW-5 was very low relative to the years <br />1983 through 1987. Flow was observed on June 3, 1991 and a water <br />quality sample was taken. Flow was measured at 0.045 cfs. At all <br />other monitoring times during the year the stream was dry. <br />Suspended solids in surface water within Stevens Gulch at SW-5 was <br />quite low. The dissolved solids of 776 mg/1 fn the surface water <br />quality sample taken at SW-5 was sufficiently high and contained <br />enough sodium and sulfate to indicate an interaction with shallow <br />• colluvial ground water in the lower portion of the Stevens Gulch <br />drainage. <br />Discharge from pond 85 located on Stevens Gulch near the well field <br />measured .02 cfs on May 30, 1991 and .0008 cfs on June 26, 1991. <br />Water quality samples were taken on both dates. There was no <br />outflow at other sampling times although the pond did not dry out <br />during the summer and fall. Suspended solids in the discharge was <br />quite low. Dissolved solids were about 250 mg/1 which is somewhat ' <br />lower than the dissolved solids in the nearby shallow well SM-1 <br />although their chemical compositions are similar. <br />Other ponds in the Stevens Gulch drainage which did not dry out <br />. during the summer and fall were P-7-2 and P-12-2. Also, several of <br /> the ponds associated with springs did not dry out during the summer <br />5 <br />
