State and city crews are preparing sandbags for possible flooding Friday at Capitol Lake in downtown Olympia.
The Department of Enterprise Services issued a warning of potential flooding between 6 a.m. and 9 a.m. near the state-owned lake, including Heritage Park. The lake is located at the mouth of the Deschutes River, which received its own flood warning Thursday from the National Weather Service.
Department spokesperson Linda Kent confirmed that the lake came within 1 foot of flooding Friday morning. However, there’s still a chance of flooding Friday afternoon, and crews are monitoring the lake for another high tide that’s expected about 4:30 p.m.
“Luck was on our side this morning,” said Kent, noting that the barometric pressure and river’s flow were lower than anticipated.
Flooding at Capitol Lake could affect traffic on Adams and Columbia streets as well as Thurston, B, Fourth and Seventh avenues in downtown Olympia, according to the department.
The department uses a flood monitoring tool to predict potential flooding and reduce lake levels if necessary. The flood elevation for the lake is 11.5 feet.
High tide levels for Budd Inlet are expected to approach 15.4 feet at 5:29 a.m. Friday and could reach 15.6 feet by 6:10 a.m. Saturday, according to the NOAA’s tide predictions.
