COVERING BOTTOM SEDIMENTS AS A LAKE RESTORATION TECHNIQUE

Application of flyash to lake bottoms as a lake restoration technique is discussed. Flyash application could control microorganisms and sediment nutrients associated with eutrophication; however, use of flyash would present more environmental costs than benefits. PVC-coated screens and spun-bonded p...

Zusammenfassung:	Application of flyash to lake bottoms as a lake restoration technique is discussed. Flyash application could control microorganisms and sediment nutrients associated with eutrophication; however, use of flyash would present more environmental costs than benefits. PVC-coated screens and spun-bonded polypropylene screens are acceptable, but costly, alternatives to flyash application. Use of sand, clay, or other sheeting to retard eutrophication should be investigated. 28 references, 3 tables.
