• TASK II. Monitoring Plan - A monitoring plan will be developed to <br />evaluate loading to Orono Lake. Monitoring will be conducted <br />'over a period of one year. Components of the monitoring plan <br />will include, but are not limited to, the following: <br />• Inflow /Outflow Water Quality Monitoring <br />• Inlet Bed Load Monitoring <br />• In -Lake Sedimentation Rate Monitoring <br />• Sediment Analysis <br />• Analysis of Other Contaminates <br />The plan for the inflow and outflow monitoring will include a <br />monthly grab sample at an estimated five stations. The first <br />monthly grab sample will be conducted just prior, during, and <br />just after peak flow during spring run -off 1997, the suspected <br />largest sedimentation loading period. In addition to the grab <br />sampling, six storm event samples will be collected through the <br />one year monitoring period. Parameters which will be included <br />in the inflow and outflow monitoring include nutrients and <br />suspended solids. <br />• Inlet bed load monitoring stations will be located at major <br />tributaries to Orono Lake. It is anticipated that a minimum of <br />four bed load monitoring stations will be established. In -lake <br />sediment rate monitoring stations will be established at five <br />locations within the lake. Both the sediment rate and bed load <br />monitoring stations will be inspected quarterly during the <br />monitoring period. <br />The sediment analysis will be conducted to determine disposal <br />options for the anticipated dredging of Orono Lake. <br />The resulting data from the monitoring plan will produce a <br />nutrient budget for Orono Lake and document the necessary <br />improvements to the drainage area so that the dredging of <br />Orono Lake will not have to be an on -going activity. <br />TASK III. Monitoring - Monitoring of the inflows, outflow, sediment <br />loading, and in -lake monitoring, will be conducted over a period <br />of one year as well as analysis of sediment. <br />TASK IV. Mapping and Calculating Past Sediment Rate - Contour lines <br />is will be digitized off the original lake map and new lake map <br />from the DNR so that the volume of sediment deposited since <br />11- 28sr/bz/stever <br />
