5.4 Monitoring and Data Collection
Hydrologic Data Program
To monitor progress toward meeting water quality and quantity goals, routine water quality and quantity monitoring of Painter Creek will continue to be a part of the District’s annual Hydrologic Data Program. Macroinvertebrate monitoring should be completed on Painter Creek every three years.
The monitoring program should be adjusted to evaluate the effectiveness of the proposed Highway 26 wetland restoration project prior to expansion of this type of restoration to other locations. This monitoring should include continuous flow monitoring with automated sampling upstream and downstream of the wetland; flow monitoring downstream of the diversion weir to measure discharge to the creek bypassing the wetland; and a precipitation station. The monitoring should be carried out for at least three years.
Comprehensive aquatic vegetation data is not available for Jennings Bay. To assess the role aquatic vegetation plays in internal phosphorus loading an aquatic vegetation survey should be completed and a management plan developed as part of any internal load reduction project. The survey should be updated after five years at an estimated cost of $8,000.
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.
