VII-3 . and the hydrog"ologic features of the bao in, we have estimated that toe base flow in Nettle Creek, above the 7,000 foot level, is 1.0 cfs per square mi Ie in an average year, and 0.9 cfs per square mile in a dry year. This base flow which is always in the stream, is mainly made up of water from the numer- ous springs in the basin. The following Table VII-A is an estimate of the amount of water that can be rel,ed upon physically, not legally, to be available in Nettle Creek, even in the driest years and the coldest winters.

(Discussed in Section V). There are few flow ncords avai lable on the springs now in use, but from the records that are available Figure VII-A on the next page was plotted showing the variation in the flow rate from the springs during the course of a year. It can be seen from the curve that in an average year, the highest flows are available in June or July and that the flow at that time is around 1.1 million gallons per day. The lowest flow rate is found in April and is in the range of 0.6 million gallons per day. . III a dry year, it is expected that the graph would move lower, approximately 10 percent, and the peak would move somewhat to the left. The high June and July flows would probably be in the range of 1.0 mgd, while April flows would be around 0.5 mgd.
