Re: BEACHNET==> Signage for creeks that run through beaches and are impacted by rain. Do you have a

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

We have a few creeks and/or storm drains that run across our beaches seasonally.  They are usually flowing only in the winter with a couple that flow most of the year.  After they flow, sometimes they form large ponds until they dry out.  We have the same problem in that the kids play in the water because it is considerably warmer.  We are constantly trying to educate the parents that the water ponded in front of storm drains are full of bacteria.  When the storm drains flow we post a sign that states "CONTACT WITH STORM DRAIN WATER, RUNOFF AND THE AREA WHERE RUNOFF ENTERS THE OCEAN MAY CAUSE ILLNESS, NO SWIMMING."  The sign also has an illustration of a swimmer with a slash through it.  The message is also repeated in Spanish.  A picture of the sign can be seen here:

In addition, most of our major storm drains and creeks are posted with a permanent signs that states "Historical sampling data results gathered at this location indicate that bacterial levels exceed health standards.  The County Health Officer cautions that contact with ocean water at this location may increase risk of illness.  Visitors are advised to stay a minimum of 50 yards away from both sides of creek mouths or storm drains."  The sign also has the same illustration of the swimmer and the message is repeated in Spanish.  I have attached a picture of that sign.
 
When we have a rain event, we issue a Rain Advisory warning people not to go in the ocean during rain and 72 hours after rainfall ends.  We post the information on our website, hotline, and ask our PIO to issue a press release.  Sometimes it's picked up by the media and broadcast,  sometimes not.

Hello,

We have a few beaches that have freshwater creeks running through them.  Of course the kids are in the creeks more than the chillier beach water.  A few of these beaches drain from heavily populated, urban watersheds.  We want to put signs up to teach people about the increased bacterial levels that occasionally occur after a heavy rain.

If you don't have signs, do you have catch phrases like, "When it rains, it drains.  Give the creek 48 hours after a rain before playing in the water." 

Do you post the creek or have auto closures based on rain events? 

Thank you for your help!
