LCA Claims “Seasonal Lake Lowering Policy Does Not Allow Lake Conroe to Refill Through Rainfall in Spring, Fall”

Never says never. Especially in a lawsuit. It didn’t take long to disprove that claim! Two days after LCA filed the claim on April 28th, the SJRA had to open its gates to keep Lake Conroe homes and businesses from flooding. And they are still releasing water…three weeks later.

SJRA Dashboard as of 6pm Friday night, 5/21/2021. Normal level is 201. Despite near constant releases this month, the lake’s level has remained above average.

This afternoon, I read the third supplement to the petition by the Lake Conroe Association (LCA) in its lawsuit against the San Jacinto River Authority (SJRA) and nearly busted a gut laughing. After a week where we received more than half the rain for the year so far, I needed the comic relief. And got it.

Two licensed professional engineers – with more than 80 years of experience between them – filed affidavits. They claim that the SJRA’s seasonal lake lowering policy “does not allow Lake Conroe to refill through rainfall in the Spring and Fall.” Their claim is repeated over and over again in affidavits by others.

Lake Conroe Association’s Third Supplement to its Original Petition

SJRA Forced to Go Beyond Seasonal Lowering to Avoid Flooding

Twice this month, the SJRA has had to release water from Lake Conroe above and beyond the seasonal lowering policy to prevent flooding. After the May Day event, they released almost 10,000 cubic feet per second (CFS) for several days to keep the homes and businesses around Lake Conroe from flooding.

The boats are in slips, but the docks are underwater. Near Monty’s Lighthouse and Fajita Jacks on Lake Conroe on 5/1/2021, when the water level exceeded 203 feet halfway through the Spring seasonal lowering.

The rains this week have been more spread out, but the SJRA still had to release almost 3,000 CFS most days to reduce flood risk around Lake Conroe.

Engineers rarely deal in absolutes. They deal in extremes and qualify almost everything they say. But these intrepid professionals stepped over the edge on the far side of reality. Mother Nature always gets the last word.

One of Many Exaggerated Claims

The LCA lawsuit seeks to stop the SJRA’s seasonal lake lowering policy. The “refill” claim is just one of many exaggerated claims that LCA has made.

This lawsuit overflows with self-destructive claims and internal contradictions.

Say That Again!

The latest filing claims that the Lake Conroe Association has the authority to speak for all of its members because LCA feels it proved actual or imminent damages to at least one of its members. In logic, they call that “the fallacy of generalization.” I know at least one influential member of LCA who disagrees vehemently with the lawsuit. So which of those two individuals should we listen to?

LCA also asserts that the Association’s rights are “in every practical sense identical” with “its members.” Its interests, however, may not be.

Some may not find flooding enjoyable.

In its original petition, LCA claimed that its purpose was “over-seeing, directing, initiating, and promulgating programs that directly affect the control, use, and enjoyment of Lake Conroe…” Had it not been for the seasonal lake lowering policy, many homes and businesses upstream or down would likely have flooded after the May Day rains.

In the same sentence about enjoyment, LCA also claims that Lake Conroe is operated exclusively for the benefit of the citizens of Montgomery County, Texas.

Did they really mean to say that Lake Conroe is operated exclusively for MoCo residents when the City of Houston owns two thirds of the water in it?

At one point, the lawsuit claims the sole purpose of Lake Conroe is to supply drinking water. But most of LCA’s complaints refer to lost recreational opportunities.

The second supporting document LCA filed sought relief for irreparable damages but did not specify what those were. Previously LCA members have complained about:

Could Dredging Costs Be The Real Issue?

But LCA’s latest filing reveals what could be the real issue here: dredging. Reportedly, the former president of the LCA had shallow water next to some lakefront property he was trying to sell. But with the water lowered, shallowness made the property less marketable.

Shallow water especially impacts residents at the north end (headwaters) of the lake.

Some LCA affidavits claim that access channels to the lake have been cut off by siltation. This latest filing references dredging in numerous places.

Wildwood Shores claims the estimated cost to dredge area canals exceeds one million dollars. They have hired an engineering company to set up a multi-year dredging plan that would spread out the costs. But they worry that the costs may still not be affordable. Dredging companies have explained the costs of dewatering the dredged materials; hauling them out of the floodplain; and the Army Corps’ permitting process.

Residents from Wildwood Shores, an area without fire hydrants, also claim that the Sam Houston National Forest could burn down if a house fire gets out of control and the local fire department can’t find a way to draw water from the lake.

I wonder if they’ve compared the cost of dredging to putting in a water well and tank from which tanker trucks can refill. I googled “cost of water tanks” and quickly found one that holds 90,000 gallons for $35,000. That’s a lot less than a million dollars for dredging. And the capacity would be enough to fill up at least 30 of the tanker trucks they reference in the lawsuit. The engineer who filed that affidavit didn’t explore that option. Perhaps because he had something else in mind…like boating, for instance.

Let’s Focus on the Real Issues and Work Together

I’m not trying to minimize the:

  • Loss of recreational opportunities
  • Inconvenience of silt
  • Expense of dredging.

We in the Lake Houston Area have been grappling with those same issues…on top of the flooding that silt dams contribute to. They are all real.

But making claims that are false at face value; inventing one doomsday scenario after another; and ignoring reasonable, cost-effective alternatives only undermine your own credibility.

Keeping water high is a temporary solution at best. Eventually, silt will pop up all around Lake Conroe. Especially after heavy rains.

Until you start enforcing regulations that reduce the effects of egregious development (including sedimentation) and form a Flood Control District to help dredge, this problem will dog you.

Realize that we’re all in this together – upstream and down. Let’s focus on ways to mitigate our mutual problems, not fight each other for a temporary advantage.

More Than Half the Rain This Year Has Fallen in May

According to the rain gage in my back yard, more than half the rain this year has fallen this month. I recorded:

  • Year to date = 24.98 inches
  • Month to date = 12.72 inches

That’s 51%.

If that’s not impressive enough for you, consider this.

11.19 of the 12.72 inches in May fell this week.

Bob’s backyard rain gage

The week isn’t even over for another 15 hours, and it’s still raining.

Street flooding on West Lake Houston Parkway near Kingwood Drive on 5/17/21 after 5.5 inches of rain fell in about 2.5 hours.

This May Compared to 30-Year Average for May

Compare this to the 30-year running average at Bush Intercontinental Airport – 5.09 inches. We’ve already gotten more than twice the average for the month, this week.

May is usually the third wettest month of the year after June (5.93 inches) and October (5.70 inches).

The record for May is 14.39 inches in 1970. That means we’re 1.39 inches short of the record. The NWS predicts another inch may fall today in the Lake Houston Area. And we have another 8 days left in the month with a substantial chance of rain every day through next Wednesday. So this could easily become the new record…at least according to Bob’s backyard gage. (The official one is at the big airport, of course.)

Below are the official stats. They also include norms and extremes for temperature, wind, cloudiness and more.

NHC Upgrades Formation Chance of Gulf Disturbance Again

At 2 pm this afternoon, the National Hurricane Center (NHC) upgraded the chances of tropical formation for a Gulf disturbance for the third time in 24 hours. Last night, the formation chance was 20%. This morning, it was 40%. This afternoon, NHC says 60%.

Jeff Lindner, Harris County’s meteorologist expects the storm to make landfall sometime tomorrow morning near Matagorda Bay. That would put the Houston region on the dirty part of the storm. However, Lindner believes a tropical storm, if it forms, will be weak. Neither the wind, nor the rain, will likely cause much damage; sustained intensification is unlikely.

Another 1-3 Inches of Rain Likely

Main impact of this Gulf disturbance: rainfall with amounts of 1-3 inches and a few higher isolated totals. “Overall, the dry air wrapping into the system and the overall lack of organization should keep rainfall totals in the manageable range,” said Lindner. “With that said, much of the area will fall on the east side of the center track and we will have to be watchful for any sort of sustained bands that may attempt to setup and train for a period of time which would locally increase the rainfall totals. Creeks and bayous should be able to handle the forecasted rainfall.”

Tides are elevated and will remain elevated into the weekend with water levels near 3-4 feet above normal. At times of high tide, minor coastal flooding will be possible along the Gulf beaches and in the inland bays, but significant coastal flooding is not expected.

NHC Forecast More Aggressive

According to the NHC, surface observations and recent satellite wind data indicate that a well-defined low-pressure system over the western Gulf of Mexico has winds of 30-35 mph near and east of the center. The associated shower and thunderstorm activity of this Gulf disturbance remains limited, but any increase in this activity may result in the formation of a short-lived tropical depression or storm.

Regardless of development, the system could produce heavy rainfall over portions of southeastern Texas and southwestern Louisiana through Saturday. Given the complete saturation of soils with ongoing river flooding along the Texas and Louisiana coastal areas, heavy rain could lead to flash, urban, and additional riverine flooding across this region, warns the NHC.
