Waterworks Industries in conjunction with Redwood City Staff developed a monitoring system whereby all the bodies of water were inspected each week. These surveys are critical to the proactive nature of the lagoon management plan. Waterworks Industries proposes to continue that model with some additions as a result of the water quality testing requirements of the draft Lagoon Management Plan (June 2003). Each Tuesday (March through October) Waterworks Staff will contact Redwood Cities designated responsible staff member (currently Rich Del Ben) on his cell phone or e-mail, to let them know that we have started the lagoon surveys. Waterworks will survey the Western Main Lagoon first, then the Eastern Main Lagoon, then Boardwalks Lagoon, then the Rockport, Radio, Canvasback Lagoons and Waterside Lagoon. The staff member performing the survey, visually inspects each body of water at a total of forty- five (45) locations and will make notes and compare earlier recorded data to access the need for scheduling chemical applications and/or harvesting of material. Waterworks staffing shall include: a boat with a four stroke motor, one senior technician or Pest Control Operator, an additional staff technician may be included to assist in launching and retrieving the boat where no ramp exists. i. Trash and Debris Monitorine:: During the surveys, Waterworks Industries staff will continue to make observations of trash and debris for removal. The survey boat will remove small amounts of debris, whereas larger quantities will need to be removed by the workboat and appropriate staff. The debris will be accumulated and disposed of at the landfill. The amount and type of debris will be included in the monthly report to Redwood City. ii. Plant Nuisance Monitorine:: The surveys will include raking the different strata levels of the lagoons to get a determination of the Widgeon grass level, volume and algae growth patterns. A schecci disk will be utilized to measure the water clarity. The amount of sunlight that can penetrate the water column can accelerate the vegetation and algae growth, thus we can better anticipate periods of rapid vegetation growth. A thermometer will be utilized to determine the water temperature. It will also be helpful to get copies of the Water Quality sample results. The varying levels of salinity, pH, phosphates, nitrates and chlorophyll "a" are all helpful in pro actively managing the lagoons. The three things that mostly affect the growth patterns of aquatic vegetation and algae, which are: light, heat and nutrients. As we monitor these three areas we can anticipate growth patterns more precisely. After the survey is concluded, a list of recommendations are relayed to Redwood City staff regarding the status of the lagoons and where and if treatments or harvesting is necessary. If chemical applications are required, Waterworks Industries staff will notify Redwood Cities Water Quality monitor, presently Scott Cressey, by phone, with a follow up e-mail. It is protocol to give Mr. Cressey forty-eight hours notice before any treatments can occur. If harvesting is necessary, work will begin the next day and continue until complete. .- 11 of 20
