A clean, cloudless night over the water, with light air out of the N with pressure climbing. Most of the action on Rush Lake should come off structure within a cast of the bank. The day fishes best from morning through afternoon. Fish confidently and change only when the bites stop. The pre-winter feed makes autumn days generous.

In Utah, Rush Lake belongs to Tooele County. Around the bank it is open valley. Surface area runs to roughly 2.5 sq miles, so plan for one area rather than the whole. The edge covers about 7.9 miles, enough to hold several distinct areas. Nothing else we list in Tooele County covers more water. Start from Tooele, 8.7 miles down the road. Grantsville lies 12 miles off, Erda another 14 miles. The nearest boundary is well away, so one set of rules covers the water.
This is salt or soda water, not a conventional fishery: do not expect the usual freshwater species here. The basin is ephemeral: it can stand empty for years between fills. Check the nearby waters on this page for the realistic fishing options in the area. Still water like this holds fish on the edges rather than out in the open. This is a lake, so the margins and the first drop matter most. At Rush Lake the water rewards a slow, careful approach.
July is the warm end of the year here, averaging about 75°F, while January sits near 27°F. Fishing continues through most of the calendar, with quiet spells rather than closures. It should never be assumed safe, whatever the month says. The hot months push the fishing to dawn and dusk. On Rush Lake that shapes the whole year.
Nothing we hold confirms whether access is permitted. It formed naturally, so levels move with rainfall rather than with a gate. Mapping flags this water as intermittent: it can be dry for part of the year, so check before travelling. Nothing built is recorded close to the bank here. Sort the permit out before you load the car. Where tickets apply, they are sold in the nearest town rather than on the bank. Rench Spring at 7.8 miles is the sensible second choice. Check the position at Rush Lake before loading the car.
