In addition to the work performed by Barr, the cities of Shoreview and Roseville have field collected the locations of all the inflow pipes discharging to Lake Owasso. Ramsey County (Terry Noonan) completed a lake macrophyte survey between May 22-30, 2007, prior to the June 4, 2007 chemical treatment to control marcophytes. The County also continues to collect water quality in Lake Owasso and RMWD has installed equipment at three Iocations to monitor stormwater inflows to Lake Owasso. The table below provides a summary of the project budgets based on the major work tasks identified in the agreed upon scope of services. Overall the project is on schedule and moving forward as planned. However, the development of the Lake User Survey (Task 010) did require more effort than originally anticipated because of the unplanned meeting with stakeholders to collect input on the lake user survey, manager's request to development of an on-line survey in addition to the mailing, and additional postage related to the number of mailings. As a result, this task r'equir'ed unanticipated project management and the budget for work task 010 was over spent. At the present time it appears that these overruns can be compensated for by other project efficiencies on the lake sediment core collection and analysis.
