The lake should be kept at full pool provided we get enough rain:
The lake levels for Lake Houston since the completion of the maintenance work in August were a result of either temporary lowering for potential tropical systems or through natural rainfall/evaporation. Since September 1st the San Jacinto Watershed has only received significant rainfall 4 maybe 5 times to date with almost a month gap between the rainfall in October to the rainfall we received Thanksgiving week. Currently, Lake Houston is at 42.35 ft. (normal pool 42.4 ft.). Without rainfall evaporation losses are 0.5 inches per day. This is why you may have seen the lake at lower levels than you might have been expecting.
Also: news on the flood gates.
The Lake Houston Flood Gates project is still undergoing the environmental assessment and permitting process while also developing gate alternatives. There are a significant number of studies that need to occur to guarantee there isn’t an environmental impact to our drinking water as well as to the lake itself. Typically, for a project of this nature it can take anywhere from 10-15 years and we have been successful in shrinking that timeline down to 3-5 years which are still expected to complete the project within at this time albeit narrowly perhaps.
Lastly, he is checking on the Luce Bayou Interbasin Project, AKA Trinity River coming in to Luce Bayou.
