5.4 Monitoring and Data Collection

Hydrologic Data Program

To monitor progress toward meeting water quality and quantity goals, monitoring of Langdon Lake will continue to be a part of the District’s annual program.

Aquatic Vegetation

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 would be conducted as part of the proposed internal load management project.  The survey should be updated by staff/contractor after five years at an estimated cost of $7,000.  Interim monitoring could be conducted by trained volunteers.

Wetland Monitoring

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.
