Visiting a nice lake is like going to a grocery store that has everything. But what happens if the lake is lacking an item or two? Maybe one or more lake projects can address the need. Although this book has several hundred project ideas, many of them are updated project ideas that have been previously conducted one way or another. For example, dredging has been occurring for over 4000 years. Fish culture, aquatic plant management (using handpulling techniques), and waste disposal are also thousands of years old | Lake and Ponđ Management Guidebook Steve McComas a LEWIS PUBLISHERS A CRC Press Company Boca Raton London New York Washington D.C. 2003 by CRC Press LLC Library of Congress Cataloging-in-Publication Data McComas Steve.
