Releases were made from the reservoir and the(l either diverted .75 miles downstream at the <br />Comanche Pump Station or 2.5 miles downstream at the Whitlock Water Treatment Plant. Recently, <br />the Pueblo Board of Water Works undertook a project; to pipe water from Pueblo Reservoir to the . <br />Comanche Pump Station and Whitlock Water Treatment Plant to improve efficiency. However, in the <br />Finding of No Significant Impact for the project, an environmental commitment was included that <br />required the Pueblo Board of Water Works to convey up to 17 cfs .oftheirraw waterfrom Pueblo <br /> <br />10 <br />
