Locke Lake : July 28 , 1993 Page Two (from B. Haake) .Lo61te .LS'Wd has 'served as a sediment basin for RCWD for many years . Over that period ,of time the Lake has gradually filled to the point were it can nor longer serve as a sediment basin and remain as a lake. This has caused an economic hardship on the properties adjacent to the lake because of a decrease in their property values. . It will replace a defective dam with a properly designed and constructed new dam which will improve the recreational and fish life benefits of the lake . . It will preserve and enhance the property values of properties adjacent to Locke Lake. Fridley requests that the cost of the project (construction of the dam and removal of the sediment) be financed as follows: .The cost associated with the dam will be paid by Fridley and Fridley will seek contributions for this sum from Anoka County and the State of Minnesota. They also intend to assess the adjacent property owners for a "portion" of this cost. .The cost of the sediment removal from Locke Lake shall be paid as proposed in RCWD' s 509 Plan . This Plan provides that the District will finance the major portion of the cost through District-wide "ad valorem" tax levy . Fridley also requests that RCWD not implement any special assessments for this portion of the Project . .The cost of the sediment retention basin shall be paid by a District-wide tax levy . "Locke Lake is a man-made reservoir . The lake bed inundated by dam • construction was once completely privately owned , but is now largely under the City of Fridley ' s control via Quit Claim Deed, tax for- feiture andmaintenance assessments .. Locke Lake is considered a non- meandered water. The land under a non-meandered lake belongs to whomever holds the deed( s) to the lands around and under the lake. " (Above information and many other following details can be found in the Engineer ' s Report on Locke Lake dated September , 1992 as prepared by James M. Montgomery , Counsulting Engineers , Inc. ) This same engineer ' s report, when commenting on the constuction, retention of sedimentation and the excavation of same, stated that "The tendency for suspended sediment to accumulate in quiescent waters is a foreseeable consequence of dam construction. . . the major source of sediment is the creek bank and valley walls of Rice Creek . Because of continued sedimentation , periodic lake dredging would be required in order to maintain an acceptable water depth in the basin. Due to the high mobilization and excavation costs , performing frequent , small scale sediment removal projects would be relatively expensive. Escalating removal and disposal costs and an increasingly resistant regulatory environment offer no guarantees that lake-wide dredging could be sustained indefinitely .
