Re: BEACHNET==> Signage for creeks that run through beaches
Roger
In Los Angeles County, our streams and rivers are not designated for swimming, and most of the time there isn't enough water in them to do any kind of swimming. We (and other agencies and NGOs) do test the streams and creeks for bacteria as associated with source ID studies, but not for recreational or posting purposes. Maybe one of my counterparts in the rest of the state could chime in if they are looking at recreational streams/creeks/rivers in their jurisdiction?

Eric: In Hawaii, all streams are posted to stay out of the water
(rain or shine) due to possible infection with Leptospira. About 10
years ago, there was approximately one death per year due to
Leptospira infection. At that time more than 50% of the leptospira
infection in the whole US occurred in Hawaii. However, CDC reduced
their effort in Leptospira data and Leptospira infection became a
non-reportable disease some years ago. In Hawaii, we believe this
occurred because not enough infections were noted in the 49 major
states and Hawaii could always be marked with an asterk (my own comments).
In Hawaii, natural streams are still designated as swimming or
recreational water sites. These sites exceed EPA water quality
standards routinely because E. coli and enterococci grow in Hawaii's
soil and are washed into streams by natural rain, which is the source
of all streams. Our state do have sites (eg esturaries) which are not
designated for swimming. These sites are posted as no swimming sites.
My question to you is how do you categorize the streams, creeks etc
in your state? Does your state sanction recreational use of these
waters under dry conditions? Roger
