To: Plan Reviewers From: Karen Chandler, on Behalf of Grass Lake WMO Board Subject: Grass Lake WMO Board Responses to Comments on Draft Watershed Management Plan Date: December 26, 2000 c: Grass Lake WMO Board and Staff Page: 8 recreational activities, including swimming. It does not mean that the water body should be allowed to degrade to the minimum water quality guidelines. To address this issue, Section 5.2 of the plan presents "action levels" for each of the Category I and II WMO-managed water resources (policy 4(d)), which take into consideration water quality trends. Figure 17 shows the details regarding the setting of action levels. As described in Section 5.2, policy 4(h), certain water quality management actions will need to be taken, depending on the relation between the most recent water quality data, the action level, and the water quality trends. This intent of this process is to protect the lakes and prevent them from degrading. The GLWMO plan specifies action. levels for Category I and II water bodies, but not Category III, N and V water bodies, since "III's" primarily serve wildlife habitat and aesthetics functions and "IV's" and "V's" primarily serve stormwater treatment fimctions. Actions for Category III water bodies would be dictated by the proposed aesthetic and habitat monitoring results (see Table 5-5). Secchi disc monitoring is also proposed for Category llI water bodies, but is not the primary concern. Actions for Category IV and V water bodies will be as required by city maintenance plans and policies. The GLWIVIO plan encourages the city of Roseville to provide treatment of the stormwater runoff from the city's leaf compost facility and to address the issue in its local watershed management plan (Section 5.3, A. General Policies, policy 9). Since the facility is only suspected of being a source of phosphorus, the issue needs to be quantified before treatment can be required at the facility. The policy will be reworded to require the City of Roseville to quanta the issue and then address it in the city's local plan. The GLWMO has received the 1984 water quality data for Grass Lake from Ramsey County. This data, and information from the Lake Owasso strategic plan, will be incorporate it into the GLWMO plan where appropriate. The GLWMO appreciates Ramsey County's continued support of the lake management program. Table 6-1 makes note of the county's monitoring prograln. The GLWMO will monitor those lakes only nl the event the county no longer conducts monitoring.
