To: Grass Lake Water Management Organization From: Denny Palmer, Karen Chandler, Hal Kunke Subject: Work Plan--GLWMO Water Management Plan Date: September 9, 1999 Page 2 preparation. For those lakes and water bodies where data are currently unavailable, the WMO Plan will recommend data collection and modeling activities necessary to fill information gaps, but completion of such studies during the term of the Plan preparation is not .feasible, given financial and time constraints. 1.1 Inventory and classify wetlands and water bodies 1.1.1 Develop base map of hydrologic system which identifies those wetlands, water bodies, streams, and conveyances to be managed in conformance with the WMP. Test the scope of the system to be managed with the GLWMO Board. GLWMO to provide ArcView files; minimal editing to be done by Barr. 1.1.2 Establish a classification system founded in the systems of member communities and based on desired use or function, resource type, and public exposure (i.e access, parks, trails). Classification system will include general range of water quality criteria, where appropriate. 1.1.3 Propose a classification for each water body and wetland in accordance with the selected classification system, based on desired public use, and test the proposed classifications with the GLWMO Board. GLWMO Board staff to test the proposed classifications with the communities by presentations to the Environmental Quality Committee(Shoreview), the Planning Commission (Shoreview, Roseville), and the Park and Recreation Board (Shoreview, Roseville); Barr to prepare presentation materials. 1.1.4 Establish specific water quality, management or other goals based on existing standards published by jurisdictional agencies, such as the MDNR, MPCA, Metropolitan Council, or interagency working groups. 1.2 Determine existin condition of wetlands and water bodies 1.2.1 Evaluate the adequacy of existing ata for determining whether managed resources meet established goals for existing conditions. 1.2.2 Where adequate data exist, compare existing conditions with classification and goals for each managed water body or wetland; determine whether goals are met for existing conditions. Wetland analysis will be based on available flood level information. 1.2.3 Where adequate data do not exist, determine data to be collected and develop data collection plan for affected resources. Collection of the data is not included in this work scope for development of the WMP. The data collection effort will be included as a WMP implementation activity, as will the subsequent parts of the assessment, described in paragraphs 1.3 and 1.4. 1.3 Estimate future water quality conditions 1.3.1 Estimate future water quality conditions using existing data or existing models for managed water bodies and wetlands. Existing models means spreadsheet modeling, not SWMM or P8, which are substantially more complicated. Since watershed is essentially fully developed, projections may be based on statistical evaluation of data.
