precipitation for the drainage areas in question. This <br /> approach was warranted due to poor correlation between <br /> rainfall records and other data . An average precipitation <br /> value of 33 inches was used for the drainage areas west of <br /> Crystal River and a value of 30 inches was used for the <br /> areas east of Crystal River . Using these precipitation <br /> values , a weighting factor of 1 . 1 was generated for use in <br /> calculating the runoff west of Crystal River . By assuming <br /> that runoff from precipitation is entirely proportional to <br /> drainage area, the runoff for each drainage area in Coal <br /> Creek Basin was calculated . These runoff values are pre- <br /> sented for the years 1960-1970 in Table III-E-4 . <br /> The assumption relating runoff directly to <br /> drainage area is not completely accurate, however, consid- <br /> ering the data available, it is probably valid' in this <br /> instance . Areas of higher elevation will usually have <br /> higher runoff due to more rainfall, steeper slopes , less <br /> vegetation, etc . <br /> C . Water quality (1977-1981) <br /> Mid-Continent has established 11 surface <br /> water monitoring stations in the Coal Creek drainage basin. * <br /> Water samples are collected monthly and analyzed for dis- <br /> solved oxygen, pH, temperature, alkalinity, total hardness , <br /> calcium, magnesium, conductivity, chloride, nitrate, ammonia, <br /> orthophosphate, dissolved solids, suspended solids , cadmium, <br /> copper , iron, lead , manganese, zinc and sulfate. The locations <br /> *In 1982 this was reduced to 3 key stations. <br /> 1 <br /> 35 <br />
