If the minimum widths specified in the Operational Planning Regulation are not of adequate size to manage for riparian objectives, then larger widths should be recommended.
It is up to the surveyor to ensure that the widths chosen are adequate to manage for riparian objectives. *Note Part 10 of the Operational Planning Regulation provides for minimum widths only. Appropriate riparian classes pertaining to streams, lakes and wetlands can be assigned if necessary. These include ephemeral (and intermittent) tributaries, side channels and/or flood channels of the main stream, swamps (flooded woodland), sloughs (marsh or mixed woodland), valley wall-base ponds, lakeshore areas, sites dammed by beavers, and other flooded areas within the floodplain apart from the main stream channel. Off Channel/Intermittent areas that provide aquatic environments permanently or seasonally. Seep an area where the water table is at the surface, creating a saturated soil condition water, and/or seeping condition. Can also occur on flat ground (artesian spring). Spring an area where the water table is higher than the surface on a slope microsite, creating a running water source at that location (may return subsurface downslope). Riparian Management Zone an area of specified width located adjacent to any riparian reserve zone, or if there is no riparian reserve zone, located adjacent to a stream, wetland or lake within a Riparian Management Area as determined * by Part 10 of the Operational Planning Regulation. Harvesting is not permitted except in special circumstances which require joint approval by the district manager and a designated BC Environment official. Riparian Reserve Zone an area of specified width located adjacent to a stream, wetland, or lake within a Riparian Management Area, as determined * by Part 10 of the Operational Planning Regulation. Fish stream is frequented by anadromous salmonids, identified threatened or endangered fish, regionally important fish, or rainbow trout, cutthroat trout, brown trout, bull trout, Dolly Varden char, lake trout, brook trout, kokanee, largemouth bass, smallmouth bass, mountain whitefish, lake whitefish, arctic grayling, burbot, white sturgeon, black crappie, yellow perch, walleye, or northern pike. Stream channel width is defined as the horizontal distance between the tops of the streambanks as determined by the normal high water mark on opposite sides of the stream, measured at right angles to the general orientation of the banks. The key physical factors used to determine reaches in the field are channel pattern, channel confinement, gradient, streambed or gully floor materials, and bank materials. Reach is a relatively homogeneous section of a stream or gully having a sequence of repeating structural characteristics (or processes) and/or fish habitat types. Other definitions useful for completing iItem 13 streams and ItemITEM 14 other water bodies follow: There are five riparian classes (W1 to W5) for wetlands based on whether the wetland is simple or complex (see Riparian Area Management Guidebook for definition), wetland size, and the biogeoclimatic unit in which they occur. A wetland must have both hydrophylic vegetation and subhydric to hydric soils. Wetland a swamp, marsh, or other similar area supporting natural vegetation that is distinct from the adjacent upland areas.
There are four riparian classes (L1 to L4) for lakes based on lake size and the biogeoclimatic unit in which they occur. Lake a naturally occurring, static body of water greater than 2 m deep and greater than 1 ha in size, or a licensed reservoir. There are six riparian classes (S1 to S6)) of streams based on presence of fish, occurrence in a community watershed, and average channel width. Ephemeral streams of less than 20% gradient may be fish streams. Stream a water course having an alluvial sediment bed, formed when water flows on a perennial or intermittent basis between continuous definable streambanks.Įphemeral streams have defined channels, but flow for only part of the year, usually in winter and spring in Coastal drainages, and in spring and early summer in Interior ones. Definitions for stream, lake, and wetland follow, along with their associated riparian classes. The SP must identify, map, classify, and assign a riparian class (if applicable) to streams, lakes, and wetlands within the cutblock.
