r <br /> MashDee River U date <br /> Mr. Baker attended the recent Waterways Commission to offer his presentation regarding <br /> alternatives for the Mashpee River. Mr. Baker reported that the C nunissi n detemiined that <br /> theywish to try their ideas involing the dredging of the 191 Channel in 1opponesset Bay and <br /> attempt to blend the dredge spoils from the mouth of the Mashpee liver. Nr. Baker was able to <br /> discuss only the first page of his presentation(see attached)in the 10 minutes allotted to him. <br /> The Chair conirr'ned that the IFF for the 1912 Channel.and Mashpee River mouth dredging is <br /> due back by August 14. The Commission wishes to evaluate the results of the RFP. The Chair <br /> has inquired if,by the October meeting,the waterways Commission will have a conclusion <br /> available based on their initial presentation and proposal. Mr. Baker noted that the Commission <br /> should be questioned about the sediment analyses of the mouth of the Mashpee River and <br /> feasibility of blending the 1916 spoils. Committee members discussed Mr. Baker"s proposal to <br /> add to the marsh front in order to improve water quality as done in Harwich at the Herring River. <br /> The Chair questioned the results of the scenario testing to which Mr. Baker responded that the <br /> RMA 4 water quality model,a 2-dimension model, is not applicable to a stratified water body <br /> such as the Mashpee River and does not consider marsh loss,condition and bacterial issues. Mr. = <br /> Baker added that there is a combination of issues that require addressing. The Chair concluded <br /> that the Waterways Comimssion study indicates that the effect of dredging on water quality is <br /> negligible as measured by nitrogen content. <br /> Mr. Baker announced that N AA will be opening a grant program with an annual budget o $10 <br /> million,with$500,00041 nr <br />
