This reservoir is located near Lawrence, Kansas. K-10 used to end right at the lake, but it now bypasses the city of Lawrence and ends at the Kansas Turnpike aka I-70. You can still travel here off an exit at the southwest side.
El Dorado Lake
This reservoir is located near El Dorado, Kansas east of Wichita. The Kansas Turnpike goes over its north side and you can exit via US-77 or K-177 to visit this lake to take pictures of nature. If you are coming from the south end, you can also follow US-54 east of Wichita and El Dorado and find it to the north.
Cedar Bluff Reservoir
There are very few lakes on the west side of Kansas, but if you are willing to take the trip, you can find this lake located south of I-70 and north of K-4 via K-147. If you look out west, it is very hard to spot lakes that exist in Western Kansas. An honorable mention is Lake Scott State Park that is north of Scott City and is probably one of the only lakes like Cedar Bluff that exist in this region of the state. Cedar Bluff Reservoir is probably one of the biggest lakes in this part of the state and is worth visiting sometime.
Wilson Lake
This lake is located in west central Kansas south of K-18 and north of I-70 via K-232. K-181 meets up with K-232 here and is another way to get to Wilson Lake. K-232 goes an extra mile south of I-70 to get to Wilson, Kansas in which the lake or the city was named after. Although a very big lake, there appear to be even bigger lakes in Kansas than this one. It is still a great place to visit nonetheless like all the other ones mentioned and like some other big lakes, there are houses near the lake to give people inside a great view day and night.
Milford Lake
Milford Lake is the largest lake in the state of Kansas with an area of 64 square kilometres. This lake is located north of I-70, west of Junction City, and west US-77 via K-57. K-244 meets up with K-57 from I-70 and is another way to get to Milford Lake. If you draw a line of symmetry on US-81, Wilson and Milford Lakes almost appear to fold on one another on a map. Even though looking similar in that way, out of all the lakes in Kansas, this is probably one of the more special ones since it holds a record for the state. I am sure you can do all sorts of things like you can with all lakes: Ride a boat, camp, fish, hike, and most importantly, relax.
