Novato Creek-late 1880sNovato Creek has been navigable since the mid 1870s when 23 ton schooners made weekly trips to San Francisco CaliforniaTidal influence extended through and upstream of Nave Shopping CenterIn 1880 the creek was dredged to keep the wharf openSolferno
Today Dredging Conducted for Flood Control
Tidal marshlands and sloughs were diked and drained for agriculture around the 1860's

At the top of the watershed are the headwatersThis is where the creeks begin. Water is typically flowing underground at the higher points, and comes to the surface as the slope is steeper.Has low lying grasses at the top in MarinTransitions to steep slopes and fast moving water.The valley floor is lower down in the watershed.Shallower slopesSlower moving waterLots of critters living thereWhere we build our towns and citiesThe Estuary is the next part of the watershed.Very shallow slopesVery windy creekMixed with sea water from the tides to make brackish waterDifferent types of plants and animals grow and live here due to the different type of waterThe bay is the last part of the watershed.
This is the grand scheme; only the bottom portion has been approved by Congress as a project of the Corps. The BMKV portion could be added by action in the Water Resources Development Act (WRDA).
2600 acres total.
Six different habitat types included.
Sloop approaching near present day Nave Shopping CenterNovato Creek is trying to adjust to the construction of the Stafford Lake dam and additional development in the watershed area. The creek is attempting to increase cross section in several areas. The bank stabilization measures proposed should not impede the creek from adjusting Data collection by professional lab
