user writes: I was putting together a presentation on the FIM project area in Kansas City and noticed a minor issue with the Flood Inundation Mapper at three gages (Stations 06893557,06893578, and 06893590) the NWS color flood stage thresholds on the stage slider bar are incorrect but are correct in the Historical Flooding "Top 10" and "Annual Flood Peaks displays". See the attached file (NWS_thresholds.JPG) for 06893578 that shows the slider bar is gray for stages above 38 ft but Top 10 Peaks display correctly shows the color increment thresholds.

this seems to be happening at the site with extended rating. See the image below.

@mhkim01 I'm not sure it's due to this, but the TOP_CURVE value for this site is returning as 32 which is well below the major flood value returning from NWS which is 43. Is this the correct top of curve value. Maybe there's an issue with the AHPS ID?

It does look like the largest flood to occur was around 32 which is still within action stage. So, I think it would be best to check the topcurve value and if it's lower than the major value, I'll treat it as null.

Fixed with #100
