Thank you for using SeeClickFix! Unfortunately we are unable to “Fix” the problem. The water you are referring to along Wetlands Edge Road also known as San Francisco Bay Trail is a tidal marsh. A tidal marsh is a type of marsh that is found along coasts and estuaries of which the flooding characteristics are determined by the tidal movement of the adjacent estuary, in our case the Napa River and Carquinez Straights . During low tides, typically twice a day, you will see more of the mud, and depending on the wind direction, we sometimes smell the mud and naturally occurring gasses due to the decomposition of the vegetation. The area you are referring to is actually under the jurisdiction of the California Department of Fish and Wildlife; the City of American Canyon Public Works or Parks Departments are not able to mow or cut down any weeds or grasses beyond the fence line on Wetlands Edge Road. Thanks again for using SeeClickFix.
