5.4 Monitoring and Data Collection
Hydrologic Data Program
To monitor progress toward meeting water quality and quantity goals, routine monitoring of water quality in Dutch Lake and water quality and volume in Dutch Creek will continue to be a part of the District’s annual Hydrologic Data program.
Lake aquatic plant monitoring provides information needed to manage aquatic plants, evaluate control measures, and plan for future actions. This monitoring is especially useful as water quality management activities are implemented and plant communities change in response to changing water quality. A baseline aquatic vegetation survey will be conducted as part of a proposed internal load project feasibility study. The survey will be updated by staff/contractor after five years at an estimated cost of $7,000. Interim monitoring could be conducted by trained volunteers.
Wetlands with exceptional value vegetation are present in the subwatershed. Because of the importance to overall subwatershed ecological integrity of preserving these values, these wetlands will be regularly monitored for invasive species by staff or trained volunteers.
