<br />Statement of Problem: Water quality refers to the physical, chemical and biological
<br />characteristics of water. The components affect higher-level community composition, quality
<br />and interactions and represent a cornerstone resource upon which all other downstream aquatic
<br />and terrestrial resources depend. The water quality parameters are linked to upper basin inflows,
<br />reservoir dynamics, and operations of Glen Canyon Dam, and downstream tributary inputs. The
<br />relationship between operations of Glen Canyon Dam and water quality variables affecting
<br />downstream resources is a management concern. Of special concern is the current draw-down
<br />condition in Lake Powell, resulting from several years of drought. Total capacity has been
<br />reduced 40%, resulting in warm releases, deltaic sediment resuspension, dissolved oxygen
<br />reductions and salinity increases.
