Typical USGS streamgage costs with example near Okapilco Creek

Update 2021-03-09: The funding cost per gauge has gone up, to $22,500, of which usually the USGS contributes about $900.

How much would it cost to fund the Okapilco Creek gage so it won’t go offline July 31st? 300x342 Pie: Percentages of funding in various activities, in Streamgage Operation and Maintenance Cost Evaluation, by U.S. Geological Survey, for WWALS.net, 1 June 2010 About $13,600/year, more or less, mostly for field and office labor and administration, with only 10% for the field equipment. Since this gage is located in Brooks County, Georgia, the most likely funding body (after USGS itself) would be the Brooks County Commission. Yes, it’s in WWALS watersheds; no, WWALS doesn’t plan to take on funding streamgages. If some funding organization appeared that wanted to pass the funds through WWALS, which is a 501(c)(3) educational institution, that would be possible. But this seems more like a government issue.

Funding needed for Okapilco Creek gage

In USGS Groundwater Data for Georgia:

The following streamgage will be shut down on July 31, 2015 unless alternative funding can be found:

  • 02318700 Okapilco Creek at Georgia Highway 333, near Quitman, Georgia

For questions regarding this threatened streamgage, please contact Tony Gotvald at (678) 924-6648 or agotvald@usgs.gov.

Linkage between ground water and surface water –USGS

Yet more documentation on why gouging a pipeline under the Withlacoochee River, or through this Valdosta Limesink area anywhere, would be a bad idea:

In most watersheds (river basins) in Florida the interactions between ground water and surface water typically result in a single dynamic flow system. This direct hydraulic linkage results from numerous karst features (such as sinkholes, conduit systems in the underlying limestone, and springs) that facilitate the exchange of water between the surface and subsurface (fig. 1). Unique problems can arise in protecting water quality in karst areas because of the direct and rapid transport of recharge through conduits to the subsurface and through resurgence by springs. In some areas, recharge from unknown drainage pathways to areas of discharge may contribute to chemical and biological contamination of water supplies. Such contamination in karst areas has been documented by many studies.

Yes, it says Florida, but the geology doesn’t stop at the state line, as USGS spelled out in a 1999 study of the Withlacoochee River. It works like this in Georgia, too: Continue reading →

Spring Flood Potential Outlook for Withlacoochee River by NWS

There is potential for “a high impact basin-wide flood event this spring should heavier than normal rainfall occur” in the Withlacoochee Basin.

Regional aquifers crossed, according to Sabal Trail

300x388 Figure 2.2-1, in Regional Aquifers Crossed by the Sabal Trail Project, by John S. Quarterman, for SpectraBusters.org, 20 February 2015 Sabal Trail seems to have a very constrained idea of the Floridan Aquifer that doesn’t include areas in for example Colquitt, Brooks, and Lowndes County that USGS says are in the Floridan Aquifer. But at least Sabal Trail is admitting its fracked methane pipeline would cross numerous aquifer systems.

Withlacoochee River sewage spills, Suwannee River Basin flooding study, and Valdosta’s funded plan to fix its problem

Someone referred to the mid-February Old Statenville Road spill in asking:

What’s happening in your watershed? This is the most recent of several sewage overflow issues I’ve been reading about.

Brief answer: this flooding issue is one of many reasons WWALS Watershed Coalition was formed; we’ve been on it since then; the City of Valdosta is being fixed the immediate problem; however there’s a much bigger problem throughout the entire Suwannee River Basin that the Army Corps of Engineers is studying.

Long answer: This has been going on for years, especially starting with the 700-year flood in 2009, which overflowed the City of Valdosta’s Withlacoochee Wastewater Treatment Plant (WWTP) and backed up sewage out of manholes, in addition to rivers and streams running over roads and bridges; see this USGS two-pager on that.

Alapaha River water levels

Update 2025-09-21: Graphs from water.noaa.gov.

300x655 Example 2014-11-03, in Alapaha River Water Levels, by John S. Quarterman, for WWALS.net, 3 November 2014 Update 2016-12-23: graphs from water.weather.gov.

Update 2016-05-31: See sea level gage reports.

Update 2015-04-28: Added flood stages and tentative highest safe and lowest boatable water levels, both above the charts for each gauge and in a summary table. If you have data, please let us know.

Here are water level gauges for the Alapaha River in Georgia and Florida, north to south. The graphs should show the current levels at this time, in feet, plus for most of the gauges a bar graph of selected historic levels.

This is a draft of a concept for use with the Alapaha River Water Trail. See also Alapaha River Rainy Season.

It is also a companion to the similar set of graphs for the Withlacoochee and Little Rivers.

USGS warns Withlacoochee River already leaks into Floridan Aquifer

There’s a reason Valdosta’s water wells are 400 feet deep. Its earlier, shallower wells were sucking up Withlacoochee River water that still leaks into groundwater. Should we risk a fracked methane pipeline digging under that same river and possibly causing more sinkholes and underground movement of contaminants, some perhaps coming from the pipeline itself or its demands for pressure testing water?

The Connection Between Surface-Water Quality and Ground-Water Quality in a Karst Aquifer


Figure E-1. Estimated percentage of Withlacoochee River water in ground water in the Upper Floridan aquifer, June 1991. (Modified from Plummer and others, 1998.)
The Upper Floridan aquifer, which is the sole source of water supply for Valdosta, Georgia, and much of the surrounding area, receives large volumes of direct discharge from the Withlacoochee River through sinkholes in the streambed or off-channel. A highly interconnected conduit system has developed Continue reading →
