Redwood City Water Quality Monitoring Program Plan © 2014 DKF Solutions Group, LLC Page 9 of 41 Bog: Freshwater wetlands that are poorly drained and characterized by a buildup of peat. Brackish Water: Generally, water containing dissolved minerals in amounts that exceed normally acceptable standards for municipal, domestic, and irrigation uses. Considerably less saline than sea water. Also, Marine and Estuarine waters with Mixohaline salinity (0.5 to 30 due to ocean salts). Water containing between 1,000-4,000 parts per million (PPM) Total Dissolved Solids TDS). The term brackish water is frequently interchangeable with Saline Water. The term should not be applied to inland waters. Brook: A natural stream of water, smaller than a river or creek; especially a small stream or rivulet which breaks directly out of the ground, as from a spring or seep; also, a stream or torrent of similar size, produced by copious rainfall, melting snow and ice, etc.; a primary stream not formed by tributaries, though often fed below its source, as by rills or runlets; one of the smallest branches or ultimate ramifications of a drainage system. Canal: A constructed open channel for transporting water. Channel: An area that contains continuously or periodically flowing water that is confined by banks and a stream bed. Culvert: A buried pipe that allows streams, rivers, or runoff to pass under a road. Ditch: A long narrow trench or furrow dug in the ground, as for irrigation, drainage, or a boundary line. Diversion channel: (1) An artificial channel constructed around a town or other point of high potential flood damages to divert floodwater from the main channel to minimize flood damages.

Access Considerations Safety Considerations Redwood Creek Drainage channel #1 Maple & Lathrop Yes Fold-up ladder will be used. City locks on gate into channel. Ladder safety. Need to be careful during high flows. Jefferson Branch Drainage channel #2 Lexington & Clinton Yes Fold-up ladder will be used. City locks on gate into channel. Ladder safety. Need to be careful during high flows. Stulsaft Branch Drainage channel #3 Roosevelt & Ruby Yes Fold-up ladder will be used. City locks on gate into channel. Ladder safety. Need to be careful during high flows. Jefferson Branch (upper) Stream #4 Jefferson (before PC church) Yes Natural area. Enter at rear of apartment parking area. Footing may be slippery, downhill to stream and sampling area. Kensington Branch Drainage channel #5 Fernside (before Massachusetts) Yes Ladder used for access. Careful during high flows Cordilleras Creek Stream #6 Industrial - west side, at City limit Yes Park adjacent to stream area.
