  <dc:description>&lt;p&gt;&lt;span&gt;The influence of water levels on population characteristics of yellow perch,&amp;nbsp;&lt;/span&gt;&lt;i&gt;Perca flavescens&amp;nbsp;&lt;/i&gt;&lt;span&gt;(Mitchill), and walleye,&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;/span&gt;&lt;i&gt;Sander vitreus&lt;/i&gt;&lt;span&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;(Mitchill), was evaluated across a range of glacial lakes in north-eastern South Dakota, USA. Results showed that natural variation in water levels had an important influence on frequently measured fish population characteristics. Yellow perch abundance was significantly (&lt;/span&gt;&lt;i&gt;P&lt;/i&gt;&lt;span&gt;&amp;lt;&lt;/span&gt;&lt;span&gt;0.10) greater during elevated water levels. Yellow perch size structure, as indexed by the proportional size distribution of quality- and preferred-length fish (PSD and PSD-P), was significantly greater during low-water years, as was walleye PSD. Mean relative weight of walleye increased significantly during high-water periods. The dynamic and unpredictable nature of water-level fluctuations in glacial lakes ultimately adds complexity to management of these systems.&lt;/span&gt;&lt;/p&gt;</dc:description>
