MVCA monitors the effect of development and land use to assess watershed conditions. This is done through field monitoring, remote sensing and gathering and interpreting information on the status of water and water related natural resources on an ongoing basis. The careful monitoring of water levels ensures that a flood forecasting and warning service is available to assist municipal officials and the general public in taking appropriate action in a flood emergency.
