I am making a map for a reservoir that has releases multiple times a day. There are 2 USGS gauges and 1 Army Corps gauge on the reservoir conveniently located at the bottom, middle (ish) and top. I'm starting to put in my offsets to account for the releases based on the average elevation over the last 1.5 years. My basic formula is: avg elev - elev during track + transducer depth. All my offsets are for individual tracks and am wondering if there is a better way to do this besides the edit track -> track properties -> water level -> then input negative offset to account for lower water levels. If this is the only way to do this is there a way to increase the decimal places in this category so it can be 1.451 instead of 1.5.

One way of dealing with this is to create a Tide Station for the reservoir by importing a text file with time and offset information. If you can create a text file with time and depth in the required format (see manual), you can them import this. Assign the tide station to all of your tracks and ReefMaster will use the provided points to offset the track depth, interpolating between surrounding tide points to calculate an offset for that time. You would then assign transducer depth (called keel offset in RM for historic reasons, even though this isn't strictly correct) to each track (you can set this in an import profile, so that it is automatically assigned as tracks are imported). If your tide station encompasses a sufficient time range, then you can use the same station for all of your tracks and assign the tide station on import when importing multiple logs.
