Is there a symbol for BG general crossing (cattle crossing or trail crossing a stream)?
A general bridge crossing symbol and a generic-crossing symbol now exists. Q. Is there a feature for TRIM streams that, in reality, are not streams? Many TRIM drainages are simply gullies that have no water and never will have. We have been calling them “undefined” channels, but perhaps “not a stream” would be more to the point? A: A stream, according to the FPC, includes intermittent channels. The problem is trying to distinguish ephemeral from intermittent channels. Previous weather conditions and time of your field visit affect the assessment. Producing maps with “not a stream” may have significant consequences. For example, there have been reported cases of “no visible channel,” while sub-surface fish have been recorded. It is recommended that the Site Card and FDIS be used to record cases where “no visible channel” occurs and to use the TRIM anomaly mapping symbol to identify these “not a stream” areas on maps.
