Three Clean Rivers 2023-12-14

Update 2023-12-22: Bad water quality, Withlacoochee and Santa Fe Rivers 2023-12-21.

Update 2023-12-15: Videos: Testing three sites in Florida and Georgia, Withlacoochee River 2023-12-14.

Update 2023-12-15: Yet another Valdosta E. Park Ave. sewage spill near Knights Creek 2023-12-11.

We got clean results for a dozen sites on three rivers in two states for Thursday: Withlacoochee, Alapaha, and Suwannee.

Valdosta saw far too much E. coli in the Withlacoochee River for Mondayafter 2-4 inches of rain, but cleaner for Wednesday.

The rest of this week had little or no rain. The next rain is predicted for tomorrow (Saturday).

So if you want to avoid E. coli, best to go early Saturday and be off the river before noon, yet still expect to get wet.

You’ll probably find cleaner water on the Suwannee or Santa Fe than the Withlacoochee River.

Of course, if the rain is small, as in less than half an inch, there may be few ill effects. But if we get another 1- or 2-inch rain, beware.

In the last week, no pollution spills were reported in the Suwannee River Basin in Florida.

In Valdosta, Georgia, a major spill of 450,000 gallons happened at one of the usual locations, near 1800 E. Park Ave. and Knights Creek, which flows into Mud Creek, the Alapahoochee River, and the Alapaha River. The press release says Valdosta Utilities discovered the spill Monday, December 11. It doesn’t say the spill did not end until yesterday, December 14, the day before the press release of today. I will file an open records request with GA-EPD for the report Valdosta Utilities sent them, to get the rest of the details.

Kimberly Godden Tanner got good Thursday results for the Alapaha River at Lakeland Boat Ramp and Naylor Park Beach. She says, “Both locations looked great. They are doing a great job at trash collection these days.”

Cindy Vedas tested the Withlacoochee River at her usual sites of Franklinville, Crawford Branch at Skipper Bridge Road, Staten Road, and Langdale Park, and got good results at all of them.

John S. Quarterman tested the Withlacoochee River at Clyattville-Nankin Boat Ramp, State Line Boat Ramp, and Sullivan Launch, and got good results.

Russ Tatum tested the Withlacoochee River at Holly Point, between Allen Ramp and the Suwannee River, and got excellent results.

Reina Lingle got good results for the Suwannee River at Royal Springs and Ivey Memorial Park in Branford, Florida.

WWALS Testing Committee Chair Suzy Hall reviewed all the results and some were recalibrated in the ensuing discussion.

WWALS Executive Director Gretchen Quarterman delivered testing supplies to several testers and trained several.

As previously noted, Valdosta’s last downstream tests were September 1, 2023. Continue reading →

Yet another Valdosta E. Park Ave. sewage spill near Knights Creek 2023-12-11

Update 2023-12-20: End date and waterway affected of Valdosta 425,000 gallon sewage spill 2023-12-11.

Update 2023-12-19: Valdosta reports to GA-EPD about two recent sewage spills 2023-12-02.

Update 2023-12-15: Videos: Testing three sites in Florida and Georgia, Withlacoochee River 2023-12-14.

Are we going back to the bad old days of Valdosta sewage spill reports so vague you can’t tell where they are, and reported many days later?

Valdosta spilled almost half a million gallons of sewage Monday, didn’t get around to telling the public until today, and then only with a press release that doesn’t say which part of town or which waterway was affected.

Oh, and Valdosta had another spill two weeks ago that was only reported to GA-EPD on this Tuesday, and so far as I’ve seen not to the public at all.

The Valdosta press release for the big spill of Monday says it was “in the 1800 Block of Park Avenue.” 1800 West Park Avenue is next to Sugar Creek in the Withlacoochee River Basin. 1800 East Park Avenue is the vague location previously reported for many sewer spills related to the collapsed sewer main near Knights Creek in the Alapaha River Basin.

The press release does not name any creek, so we can’t tell by that. We can infer by the rest of the sentence that E. Park Ave. was meant, because “inspecting manholes and sewer lines on the current Bypass and Sanitary Sewer line upgrades project” probably refers to the work related to those previous spills.

Rescheduled: Langdale Park to Sugar Creek Chainsaw Cleanup, Withlacoochee River, 2024-01-21

Update 2023-01-19: Try again: Langdale Park to Sugar Creek Chainsaw Cleanup, Withlacoochee River 2024-01-27.

Rescheduled due to water too high, temperature too cold, and rain too likely.

Come help us remove some deadfalls that are impeding canoe and kayak paddling. There are probably also new ones after Hurricane Idalia. And maybe we won’t get rained out this time.

Bring a chainsaw if you really know how to use it. Or a handsaw, or sawzall.

But you do not have to use any kind of saw to join us.

When: Gather 9 AM, launch 9:30 AM, end 1 PM, Sunday, January 21, 2024

Dark adaptation and bright lights 2023-12-15

If you go somewhere truly dark, like the Okefenokee Swamp, or even Banks Lake after dark, you, or at least other people, are trying to get dark adapted, so they can see the stars, planets, meteors, etc. That takes many minutes, and can be destroyed in seconds.

Most people these days live in cities with lights on all the time, even at night, so they are not used to dark adaptation. Here’s how it works.

It takes 7-8 minutes for the rods that enable dark vision to become sensitive enough for dark adaptation to become obvious.

It takes another 13-22 minutes (20-30 total minutes) for the rods to reach maximum sensitivity.

During all that dark-adaptation time, bright light can reverse the process rapidly.

“So if you’re trying to get dark-adapted, it’s crucial to avoid light—it can undo hours of dark adaptation in seconds. All the rhodopsin you have built up over the previous 30+ minutes disappears, and it will take time for your retina to replenish it.”*

So if you’ve come on a dark outing, please do not shine bright white lights.

Especially, do not shine such lights in people’s eyes: you will destroy their night vision, and it can take half an hour for it to recover.

If you are sitting around a campfire and need more wood, the firelight should be enough to see.

If people are in the woods looking at the stars, do not walk up on them with a bright light. That’s like running up on kayaks or canoes in a power boat. Sure, the wake will subside, but everybody knows not to do that. Getting back night vision takes even longer.

If you must use a light on such an outing, please use a dim red light, which has the least effect on night vision. Continue reading →
