affjected agencies and units of government. 2.By 1995, develop and implement an annual testing of fish in Lake Minnetonka for concentrations of heavy metals and chemicals, as needed, to assure health of those eating fish from !be lake. 3.By 1996, study and report on the impact of existing and possible future exotic plant and animal species introductions into the Lake Minnetonka eco-system, and particularly on fisheries production; develop recommended course of action, if needed. Shoreland Management Obketivest 1.By December 10, 1992, all of the 14 cities that have shoreland on Lake Minnetonka should have ompleted their shoreland management ordinances, negotiated and resolved issues related to flexibility provisions, received approval from DNR. and adopted the approved ordinances. 2.By 1993, alt agencies that own or otherwise control lands within the 1,000-foot shoreland protection zone of Lake Minnetonka should establish standards and criteria to manage runoff that meet or exceed the standards and criteria of the MCWD’s 509 plan and consistent with the intent of the DNR shoreland standards.

Lead Agency: LMCD Principal Cwperation Agencies: MCWD, MPCA, Suburban Hennepin Regional Park District (SHRPD), DNR, Council The MCWD is currently the only government agency that conducts routine annual water quality monitoring of Lake Minnetonka. Other agencies, including PCA, DNR, and the Coun^ have occasionally monitored Lake Minnetonka water quality. The scope of the MCWD’t monitoring efforts is severely limited by financial constraints. Currently, only six bays of the lake and seven tributary streams are sampled on a semi-annual basis. Analyses are limited to only basic limnological parameters. Tl:e LMCD should take the lead in dr*eloping a formal, written inter-agency agreement that provides for a single, integrated water monitoring program jointly but not necessarily equally funded by the cooperating agencies. The program should begin with updating the water quality assessment prepared for the lake in the early 1970 ’s, and coordinate or incorporate all existinf data ooUe^ion and water quality monitoring programs both in the lake and of waters entering the lake. An updated assessment of water quality is needed to improve the uodentanding of the interacting physical, chemical and biological processes which control lake water quality. Once the assessment is completed, an on-going comprehensive monitoring 7/11 Draft - 8
