The old road bed is mostly gravel and will dry out very quickly after a rain, except for a couple of
puddles (but watch out for "holes" that occasionally form in the gravel after heavy rains). Most of
the other "high" trails will take a few days to dry out (2-4 days). The "low" trails that run near
the river take the longest to dry out (3-7 days) and have some low areas that remain wet/boggy
for longer than that.
Caution (high water/flooding):
The Blue River is a major waterway and carries much of the runoff from Johnson
County, Kansas to the Missouri River. As such, it is subject to flash flooding during heavy
rains. Additionally, it continues to run rather high for several days after any significant rain.
Several trails run close to the river and there are several trails that cross the river, so please
be very careful. If the river is high, don't risk getting swept away by riding through the water--take
a road to the other side instead.
