<br />'Numeric water-quality standards were established by the Colorado
<br />Department of Health (1982), The standards for State waters were reviewed
<br />and amended by the Colorado Water Quality Control Commission during 1983,
<br />1985, 1986, and 1987, However, no modifications were made to the numeric
<br />water-quality standards for the Fountain and Monument Creek stream segments,
