Yesterday’s post cited the testimony of two “licensed professional engineers” in the State of Texas who claimed that Lake Conroe could not refill from rainfall in the Spring or Fall after being lowered one foot to provide an extra margin of safety, which helps prevent flooding homes on both sides of the dam. However, the lake did refill…and then some…within two days after the Lake Conroe Association (LCA) filed their affidavits in its lawsuit to prevent the seasonal lowering.

Deeper investigation reveals that neither engineer is a civil engineer. One is an electrical engineer and the other a chemical engineer.

“The Engineer Shall Not…”

Here’s why it is important. Note Paragraphs A and C below.

Paragraph A states that engineers shall practice only in their areas of competence.

Paragraph C states, “The engineer shall not express an engineering opinion in deposition before a court … which is contrary to generally accepted scientific and engineering principles without fully disclosing the basis and rationale for such an opinion.”

There was no such disclosure in their affidavits.

In fairness, the engineers also testified as residents and they had more concerns than flooding.

However, both:

• Cited their professional credentials at the start of their affidavits – without disclosing their areas of expertise.
• Drew the same conclusion about the inability of the lake to refill through rainfall – without stating the basis of their conclusions.

Mr. Elliott has retired and his license is inactive. Mr. Waitts’ license is still active.

Background

Only two days after LCA filed the engineers’ affidavits, rainfall raised the lake level two feet above normal, and threatened homes and businesses. SJRA had to release water at almost 10,000 CFS to avoid flooding them.

Without the seasonal lake lowering policy, someone on either side of the dam would likely have flooded. Dam operators would have been forced to flip a coin to see who. But the seasonal lowering – about which the chemical and electrical engineers complained – helped protect everyone. No one, to my knowledge, flooded on either side of the dam due to river flooding.
