The kinds of plants that grow in any body of water are determined by the water chemistry. Some prefer soft waters such as those found in northeastern Minne* sots, others grow in hard waters, and some thrive beet in alkali (sulfate; waters such as are found in some of our prairie lakes. The factors, then, that cause nuisance growths of aquatic plants are complex and are related not only to pliyeical and biological conditions occurring in the water out also to the nature of the surrounding land and use of it by man. State Regulations Under Minnesota statutes the aquatic plants growing in public waters are the property of the State and may be destroyed only as authorized by the ® , Hatural Resources. Details on regulations are set forth in the current Commissioner s Order on aquatic nuisance control. Application of any chemical to public waters for control of an aquatic condition or large scale cutting and pulling of plants requires a permit ™ partment of Natural Hesoui'ces. Application for a permit must be made to the depwtment on forms provided by the Technical Services Section of the Division of Game and ^sh, 390 Centennial Building, St. Paul, Minnesota, 55155. Issuance of a ^mit automatic* All applications are reviewed and often referred to depax^nt field sti^f for evaluation. Applications are sometimes denied because of proximity of ^ area to valuable fish and wildlife habitat, protection of human health, objections of other lakeshore property owners or lake users, or protection of valuable natural areas* Once a permit is obtained there are certain other steps that must be taken. Be fore control operations begin, certain Department of Natural Resources personnel be notified as specified on the permit. Chemically treated areas must be posted with signs Aimished with the permit. Such posting is necessary to restrict certain uses of the treated area until the area has detoxified. The holder of a permit is also required to report to the department the actual size of the area treated wd the amount of chemical used. A state licensed commercial sprayer nay be hired to treat an area after the proper permit has been obtained. The Department of Natural Resources also evaluates chemicals and procedures for control of aquatic nuisances, provides information on aquatic nuisance control and provides general guidance to lakeshore property owners associations. The Depart^nt of Natural Rasources does not endorse specific chemicalSf productSf or spraying or arbitrate results of control work. Liability for damage resulting from control work rests v'^.th the permittee or his agent. The costs of aquatic nuisance control projects must be paid by the benefited property owners. However, Minnesota Statutes 1961* Section 111.81 authorizes cities, villages, boroughs and towns to levy taxes for this purpose. Control Methods General information There are three general methods whereby nuisance growths of aquatic weeds can be controlled: biological, hand or mechanical, and chemical. Biological methods are not usually suitable for private control measures. Hand or mechanical control methods, such as cutting or pulling by hand or machine, can be effective and are advised where ___________________________________________________________________________COIBIlIKI&Xv _UBUdii _____________________________ i II lit >1 I ***' Cost of ch< •qiiipment used, bo boot ootimat< moreial). oprayo: otbroo and firmi Control of vigorously, and oooding stage, ropooted each y succossfUl if c Mechanical or h Mechanical in most situati pulled vegetati grows the veget boat channels b that are now co several times a of plants be re through their s if left in the off and propaga ditions on beac (^mmonly-u has a submerged scythe, and dra tangle vegetati submerged forma weed cutting eq Chemical contra Before a c must have prope specifically aj: ducts registerc public waters i for a particula Department of ^ intended for ue
