the water that was fished in the Lake Catherine, ICWW, Bayou B and at the launch i use (Rigolets Marina) ALL looked the same,...so i'm sure the water in Lake Pontchatrain is in the 'same' condition.
i drive over the US11 bridge almost everday of the week and get a very personal look at the water in Lake P.
but i agree that the actual condition of Lake P was not mentioned in the earlier reports and 'i' will try to do a better job of replying more accurately to help those who are asking,...and for those who are waiting to see how other's do before venturing out.
i had a day off from work Jan. 23, and decided to go fishing down the ICWW and towards Bayou Beinvenue. the water was green but had a lot of suspended particals in it. so this made it somewhat dingy.
i caught trout but only 2 out of about 15-20 were over 12'. long day but enjoyed being out on the water and soakin up the sunshine. oh, and running that Yamaha F200 in the corner LOL
good luck
