TNT has lowered the “Bar,” while CBS on Monday dammed its “Rivers.”

The post-Thanksgiving ax came down on TNT’s “Raising the Bar,” which the Turner net said was being canceled due to low ratings, and CBS’ “Three Rivers,” which has been pulled from Sunday nights.

“Raising the Bar” reps the latest disappointment for Steven Bochco, who hasn’t been able to score a hit since “NYPD Blue” went off the air.

“Everyone at TNT had a great experience working on ‘Raising the Bar’ with Steven Bochco and the rest of the show’s terrific cast and crew,” Turner execs said in a statement. “We’re proud of the series and appreciate the efforts of all of the creative people who were involved. Unfortunately, ratings for ‘Raising the Bar’s’ second season did not reach the levels required for TNT to renew the series.”

“Raising the Bar” opened last year to huge numbers for TNT — 7.4 million viewers (thanks to a strong “The Closer” lead-in) — but then quickly came back down to earth. Cabler hasn’t yet determined the fate of another drama on the bubble, “Dark Blue.”

Bochco exec produced “Raising the Bar” through ABC Studios and Bochco Media. Mark-Paul Gosselaar, Gloria Reuben and Jane Kaczmarek starred in the legal drama.

At CBS, “Three Rivers” isn’t completely dead yet — but it’s not flowing in the right direction.

The Alex O’Loughlin starrer has been pulled from the schedule effective immediately, although CBS said production will be completed on the show’s 13-episode order.

Drama repeats will air in CBS’ Sunday 10 p.m. slot for now. Contenders to take over the slot permanently include midseason entry “Miami Trauma.”

Eye hasn’t ordered any additional episodes of “Rivers,” and Monday’s decision to bench the show is a further sign that “Rivers” won’t be flooding the airwaves again.

“Rivers” didn’t air this Sunday, as CBS had a previously scheduled “Hallmark Hall of Fame” longform slated in its slot.

But in an attempt to push the needle the previous week, Eye swapped “Three Rivers'” timeslot with “Cold Case” — moving “Case” to 9 p.m. and “Rivers” to 10 p.m.

That made matters worse for “Rivers,” despite experiencing a more compatible drama lead-in. For its last airing, “Rivers” averaged 7.9 million viewers and a 1.7 rating/5 share with adults 18-49.

“Case” will continue in the 9 p.m. slot for now. CBS said no final decision has been made yet on “Rivers.”

Carol Barbee is the exec producer on “Three Rivers,” which comes from CBS TV Studios. Katherine Moennig, Daniel Henney, Christopher Hanke, Justina Machado and Alfre Woodard also star.
