<br />Effluent Parameters
<br />Note that Hay Gulch diverts water out of the La Plata River, and eventually returns water to the La Plata River. As Hay Gulch is
<br />therefore not really a tributary to the La Plata, it will be considered as part of the main stem. The discharge is to Hay Gulch, within
<br />Segment 01 of the La Plata River, Mancos River, MCEImo Creek and San Juan River Sub - basin, San Juan and Dolores River Basin,
<br />found in the C1sLdfications r Basin (Regulation No. 34; last update effective
