However, the Bay City gauge is strongly affected by tides from the Gulf of Mexico and readings may be inaccurate when flow at Bay City is below about 2,300 cfs. At those flows, LCRA estimates the flow at Bay City based on flow at an upstream stream gauge, not influenced by tide, minus water diverted downstream of the stream gauge.\u00A0 From January through February of 2018, LCRA estimated the flow at Bay City using the Lane City gauge.\u00A0 Due to construction activities at the Lane City Dam beginning in March 2018, LCRA will estimate the flow using the USGS Wharton gauge.</p><p>Calculation for the Two-Month Inflow includes releases for Bay &amp; Estuary requirements made from the Highland Lakes and from Arbuckle Reservoir for the previous
